Sounds like paranoia. It's probably not a BP thing unless you're in an episode and this paranoia is one of the symptoms.

When I get hallucinations, it's stuff like: As I was driving home from the pharmacy, I once saw a old teal Chevy pickup truck on the side of the road near the woods.. As I was driving toward it, all of a sudden the driver cut me off and slammed the brakes on me. Then I slammed my brakes too, only to realize there was no such pickup truck. The pickup truck vanished into thin air. Another example: When I was driving one time, I saw these 2 boys in red polo shirts dancing near the street, and it looked like they were trying to cross without their parents. (I couldn't see their parents.) I was afraid I was going to hit them, so I slammed the brakes. No such boys. Did not exist. They vanished too.

Also had hallucinations on my plane ride home from Europe. It was actually kinda funny. I saw a huge ripped hole in the back of some guy's pants and his boxers were sticking out. It wasn't real, though.

Hope that helps
