How would it be to be revived from voluntary death? (cryostasis)

Cryostasis, suspended animation, cryo-preservation or cryosleep (the marketing guy's prefer this last one as "Oh yeah, we gonna kill you in a manner we that will hopefully make it possible to revive you." is a pretty bad, yet accurate sales-pitch compared to "You'll sleep for 150 years and then you'll wake up at your destination.") has become a staple of science-fiction. While we aren't quite there yet in real life, we'll probably crack that nut as some animals, like wood frogs actually do it and some experiments with frozen rat livers were successful.

While sci-fi already has displayed people awaking from cryostasis as anything from panicking and confused (Star Trek for example) to groggy and hung-over (Revelation Space) all of these wake up scenes seem to be guesswork of the authors. Given current medical knowledge and experiences, how would it be for a person to be revived from cryostasis? Will it be slow or sudden? Were there any dream or visions like people who had near-death-experiences usually experience? How will their mental and physiological condition be as they exit the freezer-sarcophagus? Any data or science based hints will be appreciated.

Assume that revival works by slowly warming up the body, unfreezing it, and using nanotechnology to repair damage. Assume that this process will take several hours.
