My son did it occasionally, we did not get to him fast enough one time and he pee'd on the stairs.

My sister in law used to do it so often that my MIL used to have to lock her in her room.

Unless they are coming into your room with a butcher knife, setting the house on fire or wandering outside I would not worry about it too much.

Kids tend to "shut down" and even when they are "awake" they are really not.

Next time lead him back to bed.

They grow out of it.
