Hypnagogia And Hypnopompia

About the cool phenomenon of hypnagogia (the experience of the transitional state from wakefulness to sleep)…how to experience it, how to stay in it, how to experiment with it (“start napping with your arm raised in the air”,) and how to use hypnopompia (morning linger) to remember your dreams (“…putting your body into the posture it was in when you had that dream”.)

Hypnagogic Hallucinations

Brit — Mon, 25 Dec 2017 20:36:25 +0000

“Hypnagogia is the experience of the transitional state between wakefulness and sleep in humans: the hypnagogic state of consciousness, during the onset of sleep. Mental phenomena that occur during this “threshold consciousness” phase include lucid thought, lucid dreaming, hallucinations, and sleep paralysis….

…Sights

Among the more commonly reported,^[9]^[10] and more thoroughly researched, sensory features of hypnagogia are phosphenes which can manifest as seemingly random speckles, lines or geometrical patterns, including form constants, or as figurative (representational) images.

Tetris effect

People who have spent a long time at some repetitive activity before sleep, in particular one that is new to them, may find that it dominates their imagery as they grow drowsy, a tendency dubbed the Tetris effect. This effect has even been observed in amnesiacs who otherwise have no memory of the original activity…

Sounds

Hypnagogic hallucinations are often auditory or have an auditory component. Like the visuals, hypnagogic sounds vary in intensity from faint impressions to loud noises, like knocking and crash and bangs (exploding head syndrome).

Sleep paralysis

Humming, roaring, hissing, rushing, zapping, and buzzing noises are frequent in conjunction with sleep paralysis. This happens when the REM atonia sets in sooner than usual, before the person is fully asleep, or persists longer than usual, after the person has (in other respects) fully awoken.^[15]

Other sensations

Gustatory, olfactory and thermal sensations in hypnagogia have all been reported, as well as tactile sensations (including those kinds classed as paresthesia or formication).

Cognitive and affective phenomena

…something that you agreed with in a state of Hypnagogia may seem completely ridiculous to you in an awake state. Hypnagogia may involve a “loosening of ego boundaries … openness, sensitivity.., Subjects are more receptive in the hypnagogic state to suggestion from an experimenter than at other times, and readily incorporate external stimuli into hypnagogic trains of thought and subsequent dreams. he alpha wave stage and later in theta.” – Wikipedia

Below are excerpts from an interesting article – “Hypnagogic Hallucinations: Causes, Types, & Treatment” in Mental Health Daily.

“…During hypnagogic hallucinations, it is believed that brain waves transition from fast-paced, high frequency waves to slower-paced, low frequency waves…

…If a person wants to extend the hypnagogic hallucinatory state, they’ll typically increase theta frequencies…

..Pineal DMT: Due to the fact that hypnagogic hallucinations have been associated with paranormal phenomena, some have speculated that the brain releases DMT (dimethyltryptamine) via the pineal gland. ..

The Connection Between LSD And Dreams

THE CONNECTION BETWEEN LSD AND DREAMS

“Dreamlike effects of LSD on waking imagery in humans depend on serotonin 2A receptor activation…

…LSD produced mental imagery similar to dreaming, primarily via activation of the 5-HT2A receptor and in relation to loss of self-boundaries and cognitive control…

…Future psychopharmacological studies should assess the differential contribution of the D2/D1 and 5-HT1A receptors to cognitiv.” – SPRINGER*

“…We investigated the semantic similarity between a large number of subjective reports of psychoactive substances and reports of high/low lucidity dreams, and found that the highest-ranking substance in terms of the similarity to high lucidity dreams was the serotonergic psychedelic lysergic acid diethylamide (LSD), whereas the highest-ranking in terms of the similarity to dreams of low lucidity were plants of the Datura genus, rich in deliriant tropane alkaloids. Conversely, sedatives, stimulants, antipsychotics, and antidepressants comprised most of the lowest-ranking substances…” – FRONTIERS**

“PSYCHEDELIC LUCID DREAM RESEARCH…
…The highest ranking substances were LSD, Mescaline, & then plants of the Datura genus. Findings showed that serotonergic & dissociative psychedelics bear the highest resemblance to dreaming…

…In general, dreams & psychedelics have a lot in common. A few of the clear similarities are the changes in perception, self-awareness, & stimulation of metacognitive functions…” – GET LUCID WITH LANA -***

Measuring Hallucinatory States During Different Sleep Phases

Brit — Sun, 26 Nov 2017 17:17:40 +0000

“A New Measure of Hallucinatory States and a Discussion of REM Sleep Dreaming as a Virtual Laboratory for the Rehearsal of Embodied Cognition”

“The current study proposes a new, tighter measure of these hallucinatory states: Sleep onset, REM sleep, and non-REM sleep are shown to differ with regard to (a) motor imagery indicating interactions with a rich imaginative world, and (b) cognitive agency that could enable sleepers to recognize their hallucinatory state.”

“The present results support earlier physiological and psychological evidence in revealing a decline in cognitive functions and an increase in simulated interactions with a hallucinatory world, en route to normal REM sleep.”
