It was difficult to believe that everything he remembered, everything he'd gone through, everything he'd done, had all been a dream. So difficult, in fact, that he simply couldn't believe it. The Doctor sat on the bed as he examined the notes that were supposed to be his, brow furrowing, eyes squinting through his wire-framed glasses. At least the man he was supposed to be was intelligent. And a scientist! If he was expected to live this man's life, that was the most likely profession - which only added to the idea that this was all fake. Even the photo did little to deter him of this conclusion - photos could be altered, after all.

If he was going to get any closer to understanding, he needed to explore. The Cave had many things to see, he was sure, and so he made his way to the door, pausing to turn back for his ID. It would just be his luck that he'd find himself locked out after this imposed curfew because he'd forgotten his ID.

Toying with the thing, he exited the room and looked up and down the hall, curiosity much too great for him to sit still any longer. With no idea what he was looking for, he started walking, tucking the ID into his pocket.

Spotting another in the hall, the Doctor approached with a casualness that might have lent one to believe he'd simply walk right past. He didn't, though, stopping and giving the man an inquisitive look.

"You're another... What was it they called us? Sleeper, isn't it? What do you make of all this?" His hand waved about, indicating everything.
