Is being controlled by your other personality normal?

I am schizophrenic, paranoid, and i possibly have multiple personality disorder. But here's my story. i had gotten enraged at my ex boyfriend for all the many things he had done to me, i could almost see my skin flaming i was so mad. At that moment i lost control, and something else took over. My head started rolling crazily and arms and legs were twitching as I fought for control. I lost. From then on (for about 15 or 20 minutes) I could see and hear what was going on, but I had no choice but to witness it. I, or we, had been sitting at a table with my guy friends, when my ex walked by our table. I/we vaulted out of the seat after a few seconds and moved to pursue and attack him mercilessly. My four guy friends had seen my odd behavior earlier and moved to hold me down, and were luckily still holding when I attacked. We would escape from their grip many times until all four had to lift me off the ground while we kicked and raged. Finally, after a while, I regained control. My friends were wondering what happened, and all i could tell them is that it wasn't me. Less significant happenings like this have occurred since then. For instance, my right hand will sometimes twitch and grab at things and I won't be able to feel it (it's an odd sensation, like my hand is a void of feeling almost). Many times I can control it though. Please tell me, is this normal?
