How Many Role Players Ignore That We Are From Another Land?

[Iscah]

The peddlar does suggest that may be the problem. That does not mean we actually are unused to all the aether - peddlars aren't always right about everything after all.
In fact, we aren't especially susceptible to high concentrations of aether. The 'nightmare' was more like a vision due to being Chosen by Hydaelyn.

I know that's the actual reason for the 'nightmare', but the thing I find strange is more that he (and Y'shtola/Thancred/Papalymo later on) remarks on it being a possibility at all.

Aether is the basis of everything in this entire world - so where would they have to come from to be affected by exposure to it?
