HH Hypnagogic Hallucinations

HH - Hypnagogic Hallucinations

HH (Hypnagogic Hallucinations), sometimes referred as HI (Hypnagogic Imagery) are the natural hallucinations a person can experience while falling asleep. They mostly occur during the first moments when the person is about to lose his/her consciousness, and can be manifested in many ways such as:

- Auditory hallucinations (hearing a dog barking, a person talking to you)
- Visual hallucinations (images flashing through your eyes, sometimes more defined, sometimes just a blur)
- Tactile hallucinations (sensations like having your body numb, vibrating)
- Olfactory hallucinations (rare, but some people reporting weird smells)

They present no harm whatsoever to the person, and are in no way related to any physiological or mental issue. Many people also experience them while they perform techniques like WILD. When hallucinations are experienced while waking up, they are called hypnopompic hallucinations.
