If you can get injured in Tel'aran'rhiod, how come you can't get healed?

You can, but the same there/not there effect that happens to items happens to people as well. So you get healed, and then the dreamworld forgets you were healed and you're injured again. Nynaeve healing Rand after he was injured by Rahvin, who'd gotten balefired and so the injuries on Rand should have dissapeared but didn't: Dreamworld lagging between what is there/not there.

Question unrelated to above discussion. Possibly also somewhat morbid. My google-fu has failed me. I've been looking for some kind of body count of how many people (human or near-human) that the WoT characters have killed, directly and indirectly. Particularly interested in seeing where Egwene after tGS stands in comparison to Elayne and Nynaeve. I know there must be some number-crunching fan who has already created a master list of this.
