Why did my boyfriend pee on the bed in his sleep?
I woke up this morning to him pulling the blankets and sheets off the bed. I was confused about why he was doing this, so I asked, but he was too embarrassed to tell me. He hinted with the sentence, "I feel like I'm twelve again." So I asked, "So you pissed the bed? ....You shouldn't be embarrassed. I'm your girlfriend. Just tell me." He shook his head yes. Then I thought I could help him by getting answers on ask.com. I asked him when the last time it happened was. He said he was twelve (which I should have gotten from the hinted sentence earlier). (Keep in mind he is a healthy 18-year-old). Then I asked him if it happened before he was twelve, then he answered with an embarrassed sounding, "I used to pee the bed a lot when I was a kid, okay?"
So what I'm trying to get at here is why did it happen? He says it's not from having bad dreams. He just woke up and realized it happened. Is there something wrong with his bladder? Or is it a childhood trauma suppressed in his unconscious he's not remembering that comes back to him in his sleep? Should he see a doctor about this? How can I help him?
