I don't think I'm quite compos menti.
This thought stems from the way I sometimes get hooked onto prayers or poems... and start chanting them in my head, or aloud if I can get away with it) and once I spent an entire 80-minute class period repeating the Lord's Prayer under my breath, staring at the floor and being quite disconnected.
The second instance is looking at the recent comments I've written. They are somewhat strange. :|
