A lot is made of the dangers of Tel'aran'rhiod, that any wounds or effects suffered in the World of Dreams are real. What are the limits of such a principle? Some specific points come to mind:

1. Could a master of Tel'aran'rhiod (such as Perrin or Egwene) just *will* someone healthy?
2. Could they *will* someone dead, as Rand has threatened to in the real world?
3. Could they will a sa'angreal into existence,\* allow a Channeller to heal or hurt beyond what they might otherwise, and let the effects propagate back to the real world? The Wise Ones vaguely warn about it being evil to pull someone into Tel'aran'rhiod, but what if you could save a life like that? What if even the weakest channeller could save a life like that?
4. Can a woman get pregnant? You could have immaculate conception *as literal fact*.
5. Could a weave be laid upon a person that would be in them when they wake up? For example, could one place a fire spell keyed to some person A in person B, and create a manchurian suicide bomber out of them?
6. Could Mat, asleep wearing his amulet, be affected by channelling? It's possible that his ter'angreal would appear on him, just like the dreaming rings. Could a real ter'angreal be willed temporarily out of existence?

\*Note, Nynaeve made a ter'angreal in the World of Dreams, so it seems fair to assume that angreal and sa'angreal can be made.
