I'm not sure if any of this will be triggering so read at your own risk.
There's one thing that has always eluded me and that is how I wake up with bruises and sometimes scars. A lot of the time I find I have a new bruise that could not have been caused by simply rolling over in my sleep and knocking myself against my desk or wall. When I went on holiday not long ago I was sat at a table with my family. I went to stretch my arms upwards and everyone stopped and starred at me in shock. Someone asked "How did you do that?" I tried to twist my arm to see and my whole elbow was covered in the darkest bruise I've ever seen. I had not noticed and I had not felt any pain at all and I think if I had knocked my elbow consciously I definitely would have felt it.
Bruises tend to end up on my legs though, occasionally on my biceps and very rarely on my face. Ones on my face are usually around my eyes. My partner is a heavy sleeper and so has not noticed anything strange although once I began to talk claiming I had "taken care of the fire" and "not to worry about anything" although I have no recollection of dreaming about a fire.
As well as bruising, scarring and occasional talking I sometimes wake up in different clothes or no clothes at all and sometimes will be at the other end of the bed. It's gotten to a point now where I am really intrigued to know what I am doing.
