A multitude of reactions can occur during a psychedelic crisis. Some users may experience a general sense of fear, panic, or anxiety. A user may be overwhelmed with the disconnection many psychedelics cause, and fear that they are going insane or will never return to reality. The fear that is felt during a bad trip has a psychotic character, coming as it does from within the mind of the tripper and not from the external environment. For example, during Albert Hofmann's first acid trip, he hallucinated that his neighbour had turned into a malignant demon, when in fact she was only a friendly woman trying to help him.
