What is hypnagogic vision? Is it anything to do with an out-of-body experience – Thomas White.
The medical term for this condition is hypnagogic hallucinations, also known as waking dreams that occur as someone is drifting off to sleep.
It is a common symptom of people who suffer from narcolepsy (a sleep disorder), but can also occur with those who are not narcoleptic. It involves seeing pictures, hearing and smelling things that are not physically present.
