This is very typical. I was on 50mg of Seroquel to sleep at each night. After taking it, if I somehow pulled off staying awake for an hour, I would have absolutely no recollection of the night.

I would have entire conversations with people and not remember any part of my night.

As far as the aggressiveness, that's a bit unusual. Just try and understand that each person has different reactions to medications, especially antipsychotics.
