I do the movie/lyric thing all the time. And I also have to sing or quote it out loud to feel 'complete'. I've not heard of 'pressurized speech' before - and I didn't realize this might be related to the bipolar. When I was a little kid, my parents thought it was really funny & fascinating - it seemed to me at the time just like I had a really good memory. I didn't realize it was all that unusual, though.

I do lose track of conversations sometimes, though, when my brain rattles through the scene or song that is prompted instead of paying attention to the next part of the what's actually being said around me.
