I have had those flashes of crazy. I feel my body get white hot and then the vision pops up. Usually it happens when I see people doing stupid things, like driving around a corner and texting at the same time. I felt the white hot, sweat, and then pictured violently pounding her face to a pulp just for being so stupid and risking other peoples lives. I don't know why stupid things that people do make me want to react this way.
