Has anyone ever been affected mentally by strobe lights?

I am not talking about seizures. I am talking about being in a room with strobe lights for a long time and just feeling kind of like you are not real or you are not really there. I went to a haunted house with strobe lights throughout the whole thing. About halfway through I just wanted to get out and I felt like it was a dream and not real. It was weird. Tell me your weird experiences.
