Why do I hurt myself in my sleep?

According to my preception it is mental obsession of yours that lies at the back of your mind and comes forth when u are asleep. Probably there might be a childhood issue of being ignored by parents or bullied by school fellows or not given attention by surroundings. you might also have some restriction of any sort in your way. well whatever it is which haunts you, but certainly it is "obsession" if we say in one word and you should tie yourself up while asleep or better is to get married so that your energies may consume in positive ways.
