Usually I live alone, but at the moment I am staying with family. They have told me that some nights I shout and scream out in my sleep, but I have no recollection of this in the morning. I am currently on Aripiprazole due to auditory hallucinations and before I was on Olanzapine. Sometimes at home, I wake up in the night randomly after hearing loud bangs on the wall that is shared with the neighbours: perhaps they can hear me shouting in my sleep and do this to wake me up? What is going on?
