It's a pretty solid bet. He does at least fall asleep really quickly, his body in desperate need of some rest. And for the first bit he doesn't dream at all, too tired and too deeply asleep to do so.

Unfortunately his body's also already been conditioned to expect a wake-up call pretty frequently.

It's only been a few hours when he wakes up with a start, the feeling of burning ice hitting him, and he pushes himself up then immediately regrets it, falling back against the pillow with a pained groan.
