Are you sure u weren't experiencing Mania?
During hypo I booked a spontaneous flight to Amsterdam, but was able to observe the idea for couple of days and see if it's affordable and won't damage my studies etc..

hmm... I have strong urge to just move when I'm really worked up, very high. just move my body, go, walk, dance.. talking helps..
Very sensitive to loud noises, very sensitive to music, I feel I'm one with the music.
Loud noises may agitate me. Too many unconnected thoughts/disrupted ideas may agitate me sometimes.
General feeling that people around are slow. Bit more risky driving

BUT - some sense of judgement is still there, which keeps me safe so to speak.
