do u know anyone who alters personality after they've fallen asleep?

A mate of mine has got his own sleep personality "Kevin"(we call him/it) it's just plain bizarre!
after a heavy session he's usually the first to fall asleep, but will still accept joints, drinks, and occasionaly contribute to a conversation, but he fast asleep! he also Never remembers anything about what happened.
anyone know if this is common?
it doesn't seem to affect him in any other way, and is hilarious for us, his he alone?
(alcohol seems to keep kevin at bay though)
