Hypnogogic & Hypnopompic Hallucinations

You know that feeling when you are just dropping off to sleep, when you're not quite asleep but not quite awake? This is what is known as a hypnogogic state.

A similar feeling can occur when you are just waking up and this is known as a hypnopompic state.

During these states it is not uncommon for certain 'sensations' or 'experiences' to occur including the feeling of another presence next to your or even temporary paralysis!

Some may say that some of the reported 'experiences' are down to ghostly and paranormal goings on, others simply that it is a hypnogogic or hypnopompic hallucination, you decide...
