The Doctor knew that his memory would come back in time. He just wished that it would come back soon. He was curled up and had started to fall asleep. He knew that he needed the sleep. There wasn't much else he could do but sleep.
He was looking very tired, he didn't seem to have noticed her come back in the room as he was already asleep. He didn't move as he was relaxed where he was.
He seemed to be dreaming again, more memories flowing through his head.

"Rose." He muttered in his sleep. He didn't seem to know who she was but he figured that she must be important . He was still dreaming and rolled over in his sleep.
When he awoke he was trying to make sense of his dreams and memories. He saw that Samantha was already awake. He figured he must have slept in awhile.
"Morning." he said.
