pain
"I had abdominal surgery and after post op I was back in my room on a dilaudid iv pump.  The pain management was great but had a bad side effect.  It caused mt to have hallucinations.   I don't know if it was to high of a dose are not,  but I was seeing weird people in my room, under my bed, I saw monsters, snakes and they all were trying to get me. I was screaming and asking for help. I had to have my wife stay with me cause I could not close my eyes to sleep.  I literally felt like I was in a Freddie Kruger movie.  I now list this as a drug allergy when asked if I'm allergic to any medications.  I never want to experience that again"
