Bruise

How does a person give themselves a bruise in their sleep? This has happened to me and I have no idea how it happened. I am not a sleepwalker, so I know it had to have happened when I was in the bed. I went to bed on Saturday night and woke up Sunday morning with a big nasty bruise on the underside of my left arm near my arm pit. It is about the size of a golf ball and looks like I was either hit or pinched really hard, but neither of those things happened. I told my husband that I was going to tell everyone he did it so I wouldn't have to tell them I somehow did it to myself. I have always considered myself "talented" when it comes to bumping in to things and hurting myself, but this one is beyond me.
