I recently had a patient who was seeing things. He was convinced he was at home and that there were bugs everywhere, and kept yelling for his wife and trying to climb out of bed. 

He knew that I didn’t believe he was at home and so finally he said “okay, I have a bunch of people here who can verify for you in person that the things I’m seeing are real”. He then introduced me to his wife and 2 children, plus a nurse from a hospital in a different city. Afterwards he said, “so do you feel better now that other people have told you I’m not seeing things”.

And I had to tell him no, because I was the only person in the room with him lol.
