"I Observer"/"I Avatar"


As a young adult, I bought crime novelist Mickey Spillane’s premier 1947 novel, I, The Jury. Before it was made into two movies, the book had sold 3.5 million copies. In a flurry of action, Spillane wrote it in 19 days.

In ways generally unrecognized, the book captures the essence of the existential “I” that we all carry around in that three-and-a-half pound of mush inside our head. The protagonist of the book’s narrative, detective Mike Hammer, featured his “I, Observer,” who witnessed the deliberately intended painful murder of Jack Williams, a close friend who had saved Hammer’s life during a WWII combat incident. Hammer’s “I, Observer” felt the injustice, pain, and grief of the murder. Hammer’s “I, Avatar,” acted to achieve revenge on the killer.

All real live humans have these two “I’s.” Our “I, Observer” is a witness to the events of life. We experience life as if we were given a ticket to watch the game of life as it unfolds. Our “I, Avatar” responds to what it sees to act on our behalf. We take actions that we think are appropriate ways to respond. The difference is that the one I is “captain of its own ship,” while the other I is the sail of its own ship, unfurling as the wind blows.
One way to recognize one’s own dual I’s is in the dreams we have every night. Our “I, Observer” consciously witnesses a dream, whether we later remember it or not. In such dreams, we are aware of the story and maybe even of our role in it. Normally, however, we do not intervene to alter what happens in the dream. Even our own actions are just witnessed, not modified, as if we were watching ourselves in a movie.

There are, however, other dream occasions, apparently relatively rare, in which “I, Avatar” takes over in a dream to steer its course in the real time of the dream. These so-called “lucid dreams” are apparently not the default mode of brain thinking in dreams. Maybe “I, Observer” is the default mode of operation in both dreams and in wakeful life.

It does seem clear that the mode sometimes switches to “I, Avatar.” Our I becomes an agent that intends to act in response to what happens to us. “I, Avatar” reasons on the issues, decides the most appropriate course of action, constructs an action plan, launches activity, and adjusts action in response to the emerging consequences.

Neuroscientists don’t know how the brain switches between observer and avatar. In fact, some neuroscientists believe that the brain has no avatar, only the observer. These scientists enlist this view to support their contention that humans lack free will. If your conscious mind has no capacity for agency, then it surely cannot exert free will. All willed action would have to be pre-determined or driven by uncontrolled forces, like the sails of a ship. Such a view precludes a captain who can adjust the sail positions.

Most neuroscientists likely agree that Observer and Avatar, if it exists, are creatures of the brain. The brain must construct those creatures the way that it constructs everything elsethat is, in the form of nerve impulse representations. This basic fact was made most compellingly by the Nobel Prize studies of David Hubel and Torsten Weisel, who noticed something astonishing as they moved recording electrodes up and down in the visual cortex of awake cats who were watching scenes on a screen. A given neuron was inactive most of the time, but occasionally fired off a burst of voltage pulses. They later proved that a given neuron was sensitive to only a small feature of the image, such as a small line segment. Other visual cortex neurons were sensitive to other small segments, and they likewise selectively responded with impulse discharge. Together, all these neurons could reconstruct the image. A key point is that the image is not in the cortex. Its representation is there, in the form of nerve impulses.

The logical extension of such facts is that the brain experiences and acts in the world via its nerve impulse representations. Both the observer and the avatar must be likewise constructed of patterns of impulses, likely differing depending on whether the I is operating as observer or avatar.

This way of thinking about selfhood also resolves the mind/brain enigma. Mind is not some ghost floating around in brain. Mind is the material existence of nerve impulse representations of experience and thought. The concept of “mind over matter” is nonsense. Mind IS matter.

No one knows how the brain decides which mode of operation to use. The Observer mode seems preferable as a default, because it is the collector of information and experience that can inform the Avatar should action be beneficial to the brain and body in which it is embedded. Without the Avatar, however, our personhood is a victim of circumstance, compelled to act in predestined ways that may not be beneficial or wise. We can argue that the Avatar is the brain’s way of saving itself from its own foolishness, of counteracting adverse circumstance, and of advancing one’s agendas. The trick of successful living is the ability to switch into Avatar mode when it is needed. When we fail in life, we should ask I, Avatar, “Where were you when I needed you?

Bad Dreams May Be Bad for Your Mental Health


Mental health professionals have historically thought of bad dreams (e.g., emotional distress, nightmares) as reflecting underlying mental dysfunctions that are buried in the unconscious and only become consciously accessible in dreams. Freud, Jung, and colleagues, popularized this view and assumed that dream analysis could unmask the mental problem and thereby open a door for treatment. There is an alternate way to think about dreams that is still compatible with the classic view, but adds a new dimension for improving mental health.

Freud’s Missed Opportunity

What classical psychiatry seems to have missed is the possibility that dream content has effects of its own that may be aggravating the very psychological problems that therapists were trying to treat. We humans consciously recognize what our brains are thinking about in episodic states of sleep interruption in which the brain becomes activated and the eyes show darting movements, as if the eyes are visually scanning the dream content. These stages of sleep are known as REM, for rapid eye movement. In REM, the dreamer is not only aware of the dream events but is often an active agent within the dreams. In these so-called “lucid dreams,” the dreamer may even be able to willfully alter dream content.

The transient state of consciousness that arises repeatedly throughout a night’s sleep enables unconscious influences to emerge in dreams. If that content is a “bad dream,” it has a reinforcing effect on the thought dysfunction that is causing problems during wakefulness. We all know that repeating negative thoughts during the awake state reinforces the flawed thinking. Conventional therapy aims to help patients redirect negative thoughts and feelings in ways that are more positive.  In dreams we normally just let the negative thoughts run their course, which has the effect of strengthening the undesirable thoughts. In fact, negative dream content during dreams may be more deleterious than the same content during wakefulness, because modern research has shown that a major function of sleep, both dream- and non-dream, is to consolidate recent short-term memories. The dream content of dreams is immediately reinforced during the return to sleep. Unlike memory consolidation during wakefulness, sleep blocks out interfering sensory and cognitive processes during the memory-vulnerable period immediately after learning.

Personal Anecdote

Because to our knowledge there is no research in this area, I can only provide anecdotal reports that this premise that dream content may be a cause as well as a consequence of emotional distress. I have had a lifetime of bad dreams, off and on. Some of my unpleasant dreams recur, such as forgetting where I parked my car, or being lost, or being in a complex, unresolvable situationall of which reinforce a feeling of inadequacy. In such dreams, my brain is teaching me to think of myself as inadequate. That is surely not healthy. No doubt there are others who have similar bad dreams, and assuredly there are other kinds of bad experiences that occur in everybody’s dreams. The point here is not to explore what these dreams mean, but to recognize that such dreams may be aggravating the emotional problems that cause the disturbing content in the first place.

In the example above, my brain is programming itself to reinforce a feeling of helplessness and inadequacy. Night after night, year after year, this becomes a psychologically destructive force. Clearly, a solution would be to make yourself stop having such dreams. How might this be done? One possibility is that you could decide to be more aware of the content of each dream, both during the dream itself and afterwards, as during a nighttime bathroom break and upon awakening in the morning. During wakeful periods right after a dream, you need to tell yourself that these dream ideas are wrong and unhelpful. Tell your brain to stop punishing yourself like this.

In wakeful states, we know that it is possible for positive self-talk to program the brain for more constructive thought. We ought to be able to program our subconscious in a similar way during its operation during sleep and in the dream review right after awakening. So in this case, you should chastise your brain for any bad dream, and consciously insist just before going to sleep that your brain only generate dreams that are entertaining, helpful, or at least neutral. The assumption is that your mind can tell its brain what to do. After all, the brain is programmable, and you get to do much of the programming. This simplistic strategy seems to be working, as the incidence of my bad dreams has markedly diminished.

No doubt, there are more robust strategies that could be developed. Learning how to have more lucid dreams could help ,because in that state the dreamer might be able to veto negative content as it starts to emerge. In addition, corrective positive reinforcement self-talk needs to be cemented in long-term memory and that can be strengthened by retrieving positive self-talk immediately after awakening from a bad dream. Also, it is important to hold such self-talk sessions under conditions where memory consolidation is not impaired by distracting activity or thought.

Why Lucid Dreams Matter


Lucid dreams are often defined as the ones you know you are having in real time. These are the dreams where you seem to be conscious. You are aware of the story line, and you are often a central character in the story. Sometimes, you may even consciously manipulate the dream content toward a more acceptable outcome.

Scientists have recorded physiological changes during sleep, and there are multiple episodes during sleep, especially early in the morning, that display brain waves similar to those when you are awake accompanied by rapid, jerky eye moves (REM). When people were awakened every time these signs appeared, they invariably said a dream was interrupted.

Incidentally, I have studied this in animals. It appears that REM sleep is an innate property of the brains of mammals. I discovered REM sleep in ruminants, which at the time were assumed to rest without true sleep. I also discovered a rudimentary form of REM sleep in armadillos, which I studied because they are among the most primitive mammals. However, only people show numerous REM episodes lasting significant times. I have even published a theoretical paper suggesting why people need so much REM sleep.

Some people claim that they don't have lucid dreams, but there are physiological indicators that everybody does dream. It is possible that lucid dreams can occur but are not consolidated in memory. What is the first thing you do when you wake up? You start thinking about something other than what you were dreaming about, such as going to the bathroom, your aching joints, having breakfast, upcoming day's events, and so on. Such distractions interfere with memory consolidation of recent thought.

A sleep-lab study in which the EEG was recorded revealed certain physiological signs that are unique to lucid dreams, as opposed to non-lucid dreams. Subjects were trained to generate, recognize, and remember lucid dreams. Subjects who commonly reported having lucid dreams were selected for specific training, which included reminding themselves before going to sleep that they were to recognize when they were having lucid dreams and signal that to sleep monitors by a specific pattern of eye movements (in dream sleep, only the eyes move continuously because a descending motor-inhibition circuit in the brainstem is activated). During early-morning sleep, when lucid dreams were more prevalent, EEG recordings during lucid dreaming revealed REM-like activity in frequency bands δ and θ, and higher-than-usual REM activity in the γ band, the between-states-difference peaking around 40 Hz. 

Voltage power in the 40 Hz band is strongest in the frontal and frontolateral region. Moreover, the 40-Hz activity during REM is more coherent with similar activity in other regions of the cortex. The specific increase in gamma activity and the increased in 40 Hz-band coherence in lucid dreaming suggests that these are this may be the physiological basic of consciousness.
This study is important because the EEG changes are not like those in regular, non-dream sleep but are similar to what occurs in conscious wakefulness. Thus, REM sleep seems to be a form of consciousness. The lucid dreams are special because the content means something, but usually expresses it symbolically or in metaphors. Your brain has escaped the editing shackles of wakefulness and is free to reveal things you might not know about. Sometimes it is things you don't want to know about. However, you brain is trying to tell you something. You don't have to be a Sigmund Freud to figure out some of the meaning.

With my own lucid dreams, when I reflect on the content, I often find they help me to recognize and deal with deeply personal issues. They can point the way to personal insight. If you reflect on the dream content right after awakening, you are likely to remember it. Lucid dream content can change your life, one small step at a time.
