For example, a patient might feel different hands are touching him (sense of touch) or probably he’s hearing voices talking to him, or even smelling an odour that isn’t naturally present or tasting something that isn’t there. This basically describes hallucinations.
DELUSION
Delusions are false reality. A patient is deluded when he thinks he’s someone else. For example, a patient wakes up and says he’s the president of America when he’s just a normal citizen. It is a false belief that a person holds on to without real evidence. It may be difficult to change even with factual evidence.

Catatonia, the patient’s experience if reality is impaired. The patient’s actions are bizarre and may refuse to move or interact with his/her immediate environment.
