One sign of mania for me that is a good test when my therapist notices signs that I haven't yet is that in his office he has 2 clocks. They both barely make a ticking sound that I don't notice normally and I think most people or no other people notice. But if I'm manic those two clocks tick out of sync and it irritates me greatly, so much that we've had to put on a sound machine before. If I can hear 2 clicks I'm manic. WEird but valid test.
