Hallucination is a profound distortion in a person''s
perception of reality, typically accompanied by a powerful sense of reality. An hallucination may be a sensory experience in which a person can see, hear, smell, taste, or feel something that is not there.
Hallucinations are different from illusions. In an illusory experience, a genuine sensation is attributed to an incorrect cause, misinterpreting a coat hanging on a door to be an intruder or thinking there is water on a hot road, due to the heat rising from the road. A delusional perception is where a genuine perception (ie. correctly sensed and interpreted) is given some additional (and typically bizarre) significance.Hypnagogic hallucinations and hypnopompic hallucinations are considered normal phenomena.The hypnagogic experience occurs between being awake and asleep, while the hypnopompic experience occurs as one is
waking up; both experiences occur within the time period between sleep and waking.
Experienced qualities vary, and include fear, awareness of a "presence," chest or back pressure, and an inability to breathe, a falling sensation or a feeling of tripping, but sometimes also joy.Hallucinations were seen as a
projection of unconscious wishes, thoughts and wants, caused by functional deficits in the brain or projection of an internal state or a person''s own reaction to another.
