I'm asking on my girlfiends behalf, she wants to learn wild, so we try some night's, but when she get's the feeling that it's starting, then she feels like throwing up, and she has to stop, but feels dizzy for a while after she's changes sleeping position.
what can this be?
She only get's this when she attempts to wild.
and no, she does not have any decieses or something like that..

if you have experienced the same, then please reply.
