Lucid Dreams,
the Great Awakening
Dreams
remedy sleep's otherwise impoverishing effects on the brain. Dreaming
with intent extends conscious will into the unconscious.
Sleep
would seem to be a brain-impoverishing condition,
because it paralyzes the body, or at least it minimizes gross motor activity
and so minimizes sensorimotor feedback. But the remedy to any impoverishing
effects seems to be contained in sleep itself. The paralysis impasse looks
to be surmountable, because sleep contains within it an arena for activity.
In The
Infant Mind Richard Restak observes,
"Six
months into the pregnancy, eye movements and breathing are linked:
rapid eye movements, combined with irregular, jagged breathing. This pattern
will persist throughout childhood; during periods of eye movements the breathing
becomes irregular and jerky. Dreams disturb the sleep, disturb the breathing
. . . this is our explanation in children and adults. But what can we say
of the fetus? Does it dream as well? . . . . Indeed, what could the fetus
be dreaming of? No neuroscientist, unaided by input from some Higher Authority,
could ever begin to answer that question."
Higher authorities aside, this observation suggests that more is going
on during fetal sleep than just dozing.
When
it occurs in fetuses, REM sleep—the stage named after the rapid
eye movements that accompany dreaming—challenges conventional psychodynamic
explanations of dreaming. The prevailing psychodynamic theories describe
dreams as exercises in conflict resolution, wish fulfillment, or the "sifting
through" of mental residues. Such psychological processing in the
mind of a fetus might have little or no significance, if it can be imagined
to occur at all. Another theory explains REM sleep in fetuses without
relying on psychodynamics. This theory proposes that dreaming is not concerned
primarily with psychological processes, but with neurophysiological ones.
In this theory dreams have the job of maintaining neural networks, particularly
sensorimotor feedback loops, that are not adequately exercised during
waking hours. The medium—brain circuitry—is the message in
this model of dreaming.
Researcher
J. Allan Hobson, in The
Dreaming Brain, notes that during dreams the brain's visual and
motor cortices are as active as they are during waking, although input
from the eyes and output to the muscles are blocked. The high levels
of neural activity, "are just what one would want if one function
of REM sleep were actively to maintain basic circuits of the brain," Hobson
explains.
"Since our daytime repertoires are not always comprehensive in calling
forth a complete set of neural actions, these circuits might otherwise
suffer through disuse." Research
conducted in 2011 substantiates this insight. Using brain-imaging
technology and lucid dreamers as subjects, researchers at the Max Planck
Institute of Psychiatry in Munich, the Charité hospital in Berlin
and the Max Planck Institute for Human Cognitive and Brain Sciences
in Leipzig determined
that actions performed in dreams activate the same brain circuits that
are active when those actions are performed awake. The dreaming
brain simulates inputs and outputs to exercise sensorimotor feedback
loops—hence
the sensory vividness of the dream world and its ability to call forth
tireless, though virtual, activity.
If dreaming
has the potential to mitigate the neurological impoverishments of sleep,
then native extraterrestrials should have little to worry about in the
way of sleep-induced neurological impoverishment.
Their
juvenilized brains should be adept at dreaming, because a typical
three-month-old infant spends about 40 percent of its sleeping time in
the REM state, in contrast to a adult brain, which spends only about
20 percent of its sleep time in REM. But the prospect of spending
a large fraction of one’s life in REM sleep might not be one
that many space settlers would find inviting, given the tumult of
typical dream experience. Feelings of relief are common enough when
waking from dreams.
But the buffeting
meted out by dreams can be prevented. Lucidity is available to tame the
bully. Becoming lucid—aware—during dreams and to take command
of events is a capacity that apparently anyone can develop. Lucid
dreams, in which the dreamer knows that he/she is dreaming, would
seem to be an intersection of sleep and wakefulness, a merger that weightless
brain enrichment is likely to encourage.
Sleep researcher
Stephen LaBerge,
working at Stanford University, not only has documented the existence
of lucid dreaming, but also developed training methods that help
sleepers trigger the experience. The adept lucid dreamer, exercising
intent, can manufacture experiences to order in the dream world.
LaBerge’s training
method involves equipping the trainee with special goggles that signal
him or her with a colored light when the trainee is in the REM phase
of sleep as determined by an EEG monitor. Using agreed-upon eye movements
as a code, the dreamer can signal back to the outside world about
events that occur in dreams. The EEG monitoring equipment verifies
that the subject remains asleep during the communication.
LaBerge offers
an attractive pitch: "Lucid dreamers are often overjoyed to discover
that they can seemingly do anything they wish. They have, for instance,
but to declare the law of gravity repealed, and they float. They can visit
the Himalayas and climb to the highest peak without ropes or guides; they
can even explore the solar system without a space suit." The world
of lucid dreaming amounts to a vast virtual-reality video game obedient
to the dreamer's will.
Propitiously,
perhaps, it turns out that avid video gamers develop a knack for lucid
dreaming. Researcher Jayne Gackenbach, a psychologist at Grant MacEwan
University in Canada, reports, "If you're spending hours a day in
a virtual reality, if nothing else it's practice. Gamers are used to controlling
their game environments, so that can translate into dreams." Gackenbach's
research on lucid
dreaming proficiency in video gamers is summarized HERE.

The stellar life cycle includes a larval phase.
Biological life constitutes the larval phase of the stellar life cycle.
