Sorry if a thread is unnecessary, I was unsure of which thread to add this to as there are several about John Hurt. Feel free to merge if necessary, mods. 
Anyway, I've heard some theories that perhaps Hurt's incarnation was the unseen fear in the room in the aforementioned episode. It does make sense that the memory of him would be the Doctor's greatest fear. Does anyone else think this might have been what was in there?
Obviously I'm not stating this as fact, there could be endless possibilities, but it's fun to ponder.
