@falon- Falon- No you are not going crazy although I bet when this happened you might have thought so, or hid under a chair. Hallucinations can appear very very real and just scare the hell out of us when they happen. They really are more common than people think. But because of their stigma from history when people were locked up for it very few people admit to it. Withdrawing from Klonopin an be very tricky and when you experience withdrawal symptoms they can be as bad as if you stopped cold turkey. This being said I would encourage you to see your doctor about it. There could be another cause so it's best to be safe about it. Please look up drug interactions and alcohol use while taking this. Was this a one time thing or have you had more hallucinations?
