Pseudophakic hallucinations are hallucinations that are not obtained through the patient’s own eyes, nose, or ears, but are often present in the patient’s brain or in one of the organs of the body. For example, if a patient can see a person in his mind, this hallucination is obviously not seen with the eyes, so the hallucination is called a pseudohallucination. The content of pseudohallucinations is not very clear, and the image is blurred and incomplete. The image of the hallucination is often incomplete, and only a part of the form is seen, and the sound of the hallucination is not clear enough. The hallucinations are not projected to the outside world, for example, the patient can see an image of a person in his or her mind with his or her eyes closed and hear the voice of someone talking in his or her head without passing through the ears. Although pseudohallucinations are not the same as real perceptions, the patient is still very sure that he is feeling them and is convinced of this. Pseudohallucinations are more commonly seen in schizophrenia.
