Negative hallucination

Description:
As opposed to visual hallucination, where the person sees something that is not there, in negative hallucination he or she does not see something that is there. Unlike a visual hallucination, where the person behaves as though the hallucination is really there, someone with a negative hallucination does not, for example, attempt to walk through someone he cannot see.
