Hi, C.!
I almost missed this question because it's so similar to a question another mom asked about a recent change in her 3-year-old's sleep pattern. Wild!
I would guess that if you ask your son in the morning if he remembered the incident, he'd tell you, "No." My son *still* at age 13 has what appears to be wakeful times in the middle of the night. He'll get up and go to the bathroom, he might even talk to me, but he's sound asleep. I guess he's a somnambulator (sleep walker). He'll also seem to wake up in the middle of the night and be in a conversation about something with someone. Or, he'll pick up his pillow and throw it! He's sound asleep, and always responds to the suggestion of lying back down.
I used to be a somnambulator, too, so I'm told. I don't do it anymore. I believe it's a deep-sleep artifact that some folks have and other folks don't have. I don't believe it's related to stress or anything like that.
I have heard that somnambulating kids can get themselves into a little trouble (like going outdoors in the cold in their pajamas). Once, my son, believing he was in the bathroom, nearly did his business on my husband's alarm clock!! But, I caught him in time!
Anyway, my son is otherwise healthy, happy, and sound, and I like to think that I am, too. So, being a sleepwalker and a sleeptalker has not really hurt either of us. It's just been something to be aware of.
