I'm asking this on behalf of a friend. She's been suffering from a disorder that hasn't been properly diagnosed, and it only occurs when she's asleep. She engages in some sort of involuntary self-injury/mutilation act which makes her scratch at her body during sleep. She can't seem to control it and her condition has been progressively worsening. Lately, there're scratches all over her body, where they used to be confined to her legs. She's been to the doctor a couple of times over the years and was provided creams and lotions, but they've stopped working. I'm very worried for her and want her to stop hurting herself, but she can't seem to control it either. Is this some sort of sleeping disorder, or other mental condition? She refuses to seek a therapist and I'm not sure whether she needs one.
