Nothing bizarre at all around it; we already know of at least one instance where a soul is disconnected from the body - the mindtrap.

It seems to me that the situation will be similar to what psychics call "entering the astral plane". In most popular conceptions or descriptions of psychic projection you project your consciousness from your body, so that you can see your body sleeping, but you yourself can travel around as a psychic entity through the real world unable to touch or move things.

The difficulty may be in returning to your body without suffering a debilitating physical shock or getting lost or trapped in the World of Dreams by a nightmare, which would destroy you while your flesh lived on without a mind or a soul to direct it.

This may be why Moghedien was terrified when they confronted two male channelers in T'A'R fighting with the One Power while in the flesh - the damage would be both spiritual and physical at the same time, making a Dreamer encountering a person's body in T'A'R
doubly threatened especially if the other person had Dreamwalking training. If Rahvin successfully turned Rand into a pig (I forget which animal it was) in T'A'R while Rand was there in the flesh, where does the illusion end? Rand not only felt himself trapped in a nightmare, but he was also physically changing - he subjected his reality to a stronger and more skilled opponents' and was almost defeated rather quickly.



I'd like to think that your spirit form can't interact with your body in any way. The main problem with TAR is that you derive neither rest nor sustenance from it - thus a Dreamer has to make themselves ready to access T'A'R and then take themselves out of that state into a normal sleep cycle to get rest. Egwene, for example, was frequently very tired upon waking after spending hours waiting for Nynaeve or Elayne because she wasn't getting real sleep. Even if your body was in T'A'R, the stress seems to be resulting from the astral projection needed to Dreamwalk. You could very well imagine yourself back into your body after being in T'A'R and find yourself doubly exhausted because your body and mind didn't get actual rest. Food doesn't sustain you in T'A'R either, because it isn't real and you could starve to death while Dreaming yourself in front of a huge feast.
