I have bipolar with psychosis. I hear voices and recently have started to see shadow people as well. This happens mainly when I'm manic. When I hear the voices and Im not sure if there is someone there speaking I look around the room and if I don't see anyone I know the voices are not real. I try to ignore them bur I do tend towards paranoia and ignoring them is hard. I usually end up taking some Haldol and that seems to get rid of the voices. Since I've been on Zyprexa I don't hear the voices often.
