Sleep Paralysis is a sleep disorder wherein the person though is awake, but they temporarily unable to speak or move. Scientifically, it is a sign that your body and mind are unable to transition through different stages of sleep.


When this condition usually occurs?

This event usually occurs when the person either falling asleep (Hypnagogic) or waking up from sleep (Hypnopompic). Hypnagogic state is when you entering REM (Rapid Eye Movement) stage sleep while Hypnopompic state is when you exiting REM stage sleep. The REM stage sleep is when the brain becomes active and is conscious enough to experience life-like visions in the form of dreams, but the body is still inactive. 

Sleep Paralysis is an anomaly happen when you wake up in the middle of the REM stage sleep. When a person wakes up when the REM stage is still active, he/she is able to see, hear and feel because the brain is awake, but is unable to move because the body has not yet come out of the REM stage. Although this sounds scary, it lasts only a few seconds because the body realises that the brain is already awake and slowly begins to move again.


There are 3 common symptoms associated with sleep paralysis.

The symptoms can be characterised by sensory, auditory, and visual hallucinations such as;

01) Intruder :- A sense of malevolent presence in the room, footstep sounds, shadows, and rattling doorknobs.

Above are the example of symptoms of visual hallucinations. This happens because the person mind is active but still in dream-state and has not fully awake. These visions or hallucinations can be the ongoing dream that the person is having.

02) Incubus :- Difficulty in breathing, pressure on the chest, sense of being smothered, sexually assaulted or killed.

Along with paralysis of the body, people may also experience tightness or pressure on their chest, as well as a choking feeling.

03) Vestibular Motor :- Out of body experience, floating or hovering, flying, rapid spinning, or falling from heights.

These symptoms are the most infrequent condition happens during sleep paralysis. The reason why certain person particularly experience this events remain unanswered. But it is also hugely debate that these conditions are just one of the visual hallucinations.
