hypnagogic hallucination

Some people may also experience hypnagogic hallucinations during this stage.

Hypnagogic hallucination may occur in this state, especially auditory ones.

It had, of course, been a hypnagogic hallucination, based on too many drinks and too little sleep.

Hypnagogic hallucinations are sometimes associated with brainstem abnormalities, but this is rare.

As in the case of hypnagogic hallucinations, insight into the nature of the images remains intact.

Hypnagogic hallucinations are often auditory or have an auditory component.

Some people under the influence of the drug are known to have had hypnagogic hallucinations, particularly that of The Presence.

That's a textbook precursor to a hypnagogic hallucination."

Hypnagogic hallucinations and hypnopompic hallucinations are considered normal phenomena.

These hallucinations usually occur in the evenings, but not during drowsiness, as in the case of hypnagogic hallucination.

The excessive daytime sleepiness generally persists throughout life, but sleep paralysis and hypnagogic hallucinations may not.

Hypnagogic hallucinations are vivid, often frightening, dreamlike experiences that occur while dozing, falling asleep.

'Sleep paralysis' is a condition that may occur in normal subjects or be associated with narcolepsy, cataplexy, and hypnagogic hallucinations.

Many of the dreams listed above, such as flying, falling sensations, or everyday activities (turning on/off lights) would be classified as hypnagogic hallucinations.

These are called hypnagogic hallucinations when accompanying sleep onset and hypnopompic hallucinations when occurring during awakening.

There are wide variations in the development, severity, and order of appearance of cataplexy, sleep paralysis, and hypnagogic hallucinations in individuals.

Narcoleptics also experience hypnagogic hallucinations, dreamlike visual and auditory hallucinations that come on quickly while dozing and falling asleep.

Hypnagogic hallucinations can occur as one is falling asleep and hypnopompic hallucinations occur when one is waking up.

They may occur when a person is about to fall asleep (hypnagogic hallucinations) or when a person is just waking up (hypnopompic hallucinations).

When lying down at night and closing the eyes, right before sleep the complex motion of these patterns can become directly visible without any great effort thanks to hypnagogic hallucination.

According to research in anomalistic psychology visions of ghosts may arise from hypnagogic hallucinations ("waking dreams" which are experienced in the transitional states to and from sleep).

Sleep paralysis and hypnagogic hallucinations also occur in people who do not have narcolepsy, but more frequently in people who are suffering from extreme lack of sleep.

Sleep paralysis and hypnagogic hallucinations may also be seen, and these symptoms are actually as common in idiopathic hypersomnia as they are in narcolepsy without cataplexy.
