having considered this for a while, despite Aviendha's impression that it was "real", it can't be. Min's stated that the pattern is in flux and that visions of the future cannot be assured any longer. Or else we all have the answer we needed - Rand won, the end.

So i figure it's still a warning and possibly specifically for Aviendha whose bloodline is not only responsible for the future of the Aiel, but who's also taken upon herself the role of setting a new direction for the Aiel.

It was interesting though - and i don't understand the (supposed) anger. It was also exceptionally creepy and quite sad.
