Has anyone here ever experienced auditory hallucination?

Hello, everyone, About an hour ago, just after midnight, I was sound asleep and was suddenly wakened by a man's voice ordering -- "GET UP!!!" I lay there without moving, absolutely terrified, for I don't know how long. I'm guessing somewhere between 2 minutes and 10 minutes. I listened intently to see if there were any noises in the apartment. I was certain at first that a man had gotten into my apartment. I finally got up the nerve to move slightly, then finally called 911. I stayed in bed, too scared to go into the living room. The 911 operator held onto my call until the police officers (two of them) checked around the building and the hallway, then knocked on my door to be sure I was safe. When I went to the door, there was my kitty, sleeping soundly in his usual spot! So I knew nothing had really happened.

I have never in my entire life had an auditory hallucination. And, since I've been an adult, never, ever was I so absolutely terrified. You've heard the expression, "My heart was pounding." Well, I've never experienced that till tonight. Yes, my heart was pounding out of my chest.

My meds are lamictal, 125 mg., escitalopram 10 mg (is that seroqouel?), and depakote 250 mg. I've been stable on these for about a month except for about 5 days of ultra rapid cycling immediately after a surgery that had nothing to do with the brain. I was in no pain from the surgery; had no anxiety about it. But the pdoc and the surgeon both told me it was physiological stress that set off the mood and personality change, and now it seems like I'm better, stable again.

I am very glad nobody had come into my apartment. But this is very disturbing. I will call my pdoc or on-call pdoc right away in the morning. I have cancelled everything else for the day tomorrow.
