Hi, for last 1 mnth my husband has started talking alone and behaves as if he is talking to someone, whom we cant see. As per him, that thing(whom he talks to) can be dangerous and thus, none of the family member should go close to him or in the room, where he sits or sleeps. He doesnot eat properly nor he sleeps well. Please help, as I am completely worried about him. Regards, Swati
