i hear ya too!!!my screaming voices are horrendous. Also i see visual faces of images of weird faces and facial expressions too. they invade my mind so much i can't concentrate. what could cause this? don't know but i am on meds for this but it doesn't help, but i have to say too they aren't as bad right after i take my meds but my meds only seem to work for a few hours. i just wish my meds would work longer and my doc doesn't want me to take more than i am used too.
