I know this feeling. For me this happens when something happens really fast unexpected response. Like I guess, a situation that I normally have been able to endure in past..but happens one to many times and some other part jumps out and reacts instinctually, but only for a matter of minutes then the situation is not over but the course NOTICEABLY altered from what I last remember...then I have to deal with the consequences...sometimes. I think what I am aiming to say here is.. this feeling happens when there is a large change, major jolt.... F IT! A FREAKIN DISRUPTION IN THE FORCE!! don't care if that sounds silly. That's what it is.
