In series 6 episode the god complex, what is in the doctor's room?

When the Doctor opened the door we could hear the Tardis bell, I'd say the Tardis was was his room

I've always wondered that to i think it might be something to do with his future something like him and river or what happens to Amy and Rory or something like that but if you find out please let me know to because i want to know as well

No one knows. The writers left out what his in him room to keep it a mystery.

If I had to guess I would probably say himself, because of the Dream Lord and the Valeyard. At times he almost seems terrified of what he'll do.

I think in room was Doctor , just like in episode Amy´s choise

I thought it could be River Song as River was potentially going to kill him and well the Doctor feared his own death! Also as he leaves the room there is a door knob sign saying "Do not disturb". River Songish I believe so! :D
