Zanaflex mixed with Cymbalta or certain pain meds can cause this. I take Zanaflex 8mg most nights, but when I was also taking Cymbalta I had vivid dreams and hallucinations.

I am trying to find a new AD, I haven't had any problems since stopping the Cymbalta...it was working very well before I started seeing things on my wall.
