Same here, and I think there are many possible factors there without all of them being applicable to everyone. Alcohol can release inhibitions of one kind or another that would otherwise keep us from doing certain things, and then I do believe "manic" played in along with that a times. For myself, however, and actually firstly, alcohol completely changed or somehow altered my perceptions of everything and everyone around me...and that ultimately led to my new-found feeling of being completely free to go places and do things (as if I had suddenly been transformed from a "nobody" to "possibly somebody")...and there is where (at least in my own case) I did some things like your running through the woods naked while howling like a wolf.
