I agree that you really should be in IP like I've said before. But to answer your question, it's not normal but it's common for us. But when I'm getting manic and haven't slept in awhile, I don't hear voices but I hear music. It sounds like a cell phone ringing. I'll catch myself hearing it so I'll mute my tv and listen for it. That's how I know it's time to call pdoc asap. This isn't anything to mess around with. Please consider IP on Monday.
