Hypnopompic hallucinations: Augmenting the terms hypnopompic and hallucinations, we are left with âhypnopompic hallucinationsâ â which can be defined as perceptual experiences with no grounds in reality that occur during the transition between a sleeping state and wakefulness.rain waves: It is thought that brain waves are altered during hypnopompic hallucinations. The brainwave pattern may include a combination of theta waves and/or alpha waves, along with intermittent bursts of beta.
Polysomnography monitors your sleep stages and cycles to identify if or when your sleep patterns are disrupted and why. The normal process of falling asleep begins with a sleep stage called non-rapid eye movement (NREM) sleep. During this stage, your brain waves, as recorded by electroencephalography (EEG), slow down considerably. Your eyes don't move back and forth rapidly during NREM, in contrast to later stages of sleep. After an hour or two of NREM sleep, your brain activity picks up again, and rapid eye movement (REM) sleep begins. Most dreaming occurs during REM sleep. You normally go through four to six sleep cycles a night, cycling between NREM and REM sleep in about 90 minutes.
