Sleep crawling

So we are pretty sure we have the makings of a sleep walker on our hands. Our little man will crawl up to the head of the bed, fully asleep. He sometimes bumps his head against the wall or flops it down onto our heads and pillows. His eyes are completely closed and he falls back asleep. Has anyone else encountered sleep crawling? I'm sure some of you have.
We finally got a mattress for the crib and are now starting naps in the crib. It seems to be going well so far (knock on wood). The plan is to work up from naps and putting him in his crib at the beginning of the night to hopefully sleeping through the night in his crib. I have no idea when that night will be, but I'm hopeful.
