whenever i read tips on how to wild it always says not to cross your legs and arms. Why? just wondering.

It’s probably because you need to relax to do WILD.
Don’t think I recall hearing that advice, I can’t really think of a reason for it either. If you’re WILDing then sleep how is reasonably comfortable. The only reason that comes to mind is, it may affect the blood flow to those parts and disrupt your wild attempt. My feelings on that would be to try it and see. If it happens then yeah change your position. 
Hmm, I think I’ve heard this. Some times when trying to WILD you’ll get a strong urge to roll over or cross your legs. This is a signal from your body to try and figure out if you’re mind is still awake. So if you cross your legs then, you won’t enter SP. If you are able to resist this urge, the body will think it’s ok to enter SP and will do so.
