Out of the Closet

We change Eric every night before we go to bed because he pees through diapers pretty quickly.  We have done it for quite some time so Eric normally doesn't even wake up when we do it.  The other night, Jeff walked into Eric's room around 9:45 and promptly freaked out because he couldn't find Eric.  He was not in his bed and not on the floor.  Knowing that he likes to play in his closet, as I have caught him doing so several times, I opened his closet door and there was resistance.  This is what we found:

He told Jeff the next day that he was playing in there, and then he got tired and put his head down!
