Why do i get dizzy when i am about to do something irrational?

This is very very strange, and has affected me for several years, but i just recently made the connection as to what was triggering it. First, If this symptom is triggered, it feels like i disconnect from my body for about 1 second. Its quick, but its extremely disorienting. My thoughts stay on track, and my mental focus is unaffected, but my eyes, balance, and spatial awareness shut down for a split second. its like if i was shot out of an ejection seat or something... its nutz. anyways, I have finally figured out that this occures every time im about to do something that could lead to a fight. For instance, lets say im driving on the interstate, and someone is driving like a retard around me. I might deside to do something ignorant just to piss them off, which if i were on the recieving end of, might really piss me off. Like if i was to deside to p someone on the interstate, and use an on-ramp to do it... something really retarded, and just as im committing to taking this action in my head, BINK! it happens. just for a split second i go bonkers, like discribed above. Or lets say im at work, and my boss comes and wants me to do something retarded, not that i refuse to do it, but that is just so dumb i cant help but let him know how stupid i think his idea is (not a good thing to do to your boss, but i just cant help myself sometimes) anyways... just as soon as i commit and begin taking verbal action, i go bonkers for a split second. I think this is something that is only detectable to me, becuase i never twitch, i dont lose my train of thought, nor stumble or studder my words, but if you were to spin me upsidedown and turn the lights on and off real quick, i might not notice becuase ive got something bigger going on inside my head for a second or so, and my brain detaches from my senses. not good right? whats up with that? its getting more and more annoying, bucuase ive been getting more and more cynical lately... which is why i finally made the connection. Im typically a well mannered conservative indivisual, nonconfrontational. but lately, ive just had enough, and F'it, im gonna say what i think, and if it makes you mad, well i dont care. but this bad attitude has been surfacing more lately, and with it comes this dizzy, disorientation. When this first started happening to me, I thought i was having a stroke or something. if you read the symptoms of a stroke, this is very similar in my opinion, but it only happens when im am about to do something confrontational.
