For year when I sleep I remove my earing and other jewerlly from my body, I also have conversation with my roommate, when she tells me about it I have no memory of it even taking place! I need to mention that when having these convocation I am actually walking about so she tells me, what could be causing this? And for the past 10 months I have been humming non stop, I hum when I m awake, I hum when I wake to go to the bathroom and also hum until I fall a sleep, I ve tried to stop but seem to have no controll over the humming, what could be going on?
