A 27-year-old woman is brought to your office by her mother. The mother tells you that her daughter has been schizophrenic for the last 8 years and is starting to decompensate despite medication. The patient states that she has been taking her antipsychotic and she is doing just fine. Her mother retorts that her daughter has become quite paranoid. When asked why, the mother gives an example about the mailman. She says that her daughter goes and gets the mail every day and then microwaves the letters. The patient agrees that she does this but only because she sees the mailman flipping through the envelopes and she knows he's putting anthrax on the letters. Her mother turns to her and says, "He's only sorting the mail!" Which best describes the patient's abnormality of perception?

An illusion is merely a misinterpretation of real external stimuli. In this case, the mailman is looking through the letters before he puts them in the box. The mother correctly assumes he is sorting the mail but her schizophrenic daughter attributes his actions to being part of a nefarious bioterrorism plot.
