I would certainly hope so! Hallucinations could indicate all sorts of serious conditions so unless you have had a VERY thorough work up I would think there is definitely some testing that should be in order. Like I said...mine were caused by seratonin syndrome...which can kill you. I didn't have it bad enough to be at that point but what if one of my stupid doctors that I had had increased one of my meds with seratonin (which...come to think of it they did and I was made violently ill after taking that med so I stopped taking it after two tries)? Not saying yours is the same situation but you should at least have peace of mind and get as much checked out as you can.
