Deception ... A distorted and distorted perception of the real thing in which the patient is aware of the external influence on the truth

Deception is a distorted and distorted perception of something real, in which the patient perceives the external influence on his or her reality. A rope may be seen, for example, as a snake.
The patient may see people around him with sullen faces and angry expressions, or on the contrary, all of them see joyful joy above their bare cheeks.
