A few yrs ago I was in the hospital and they didn't think I needed my Klonopin....I went through withdrawal and had auditory hallucinations. It started suddenly (after no sleep for 2 days, chills and legs restless). I heard 50's music in my head and my sisters voice was the DJ. It was constant and I couldn't turn it off. It was very scary to me, I don't even think the music were real songs...I hate 50's music! Anyways, I was transferred to the psych unit and they knocked me out with ativan so I could sleep and gave me seroquel, the next day it still was going on for a few hours but then stopped....completely.
