My 24 year old boyfriend, in the last 2 years, has awakened me at least a dozen times in the middle of the night by sleepwalking. I know this isn t a very serious condition, but he urinates in random placs, as well as being able to unlock doors and leave our apartment. He has hit me forcefully when I appear in the room or try to guide him back to bed. I can t sleep thinking he may hurt me or himself. What can I do?
