I've seen and sensed things that weren't there and also heard a voice as well that doesn't sound like me. I know they're not real, but they seem so real and scary at the time. Seroquel has lessened these symptoms for me. I'm also bipolar, so it doesn't mean your psychotic or anything. It's part of the anxiety/depression usually. Some people see & hear things during mania as well. You're not alone.
