The only time I've been able to WILD, I was lying on my stomach.
Last night, I was just seconds away from WILDing a second time, it was so cool, I was entering imagery where I was waterskiing, but instead of skiing on water, I was flying a couple of inches above.

Anyway, I was lying on my right side this time.

I've noticed that I absolutely cannot relax enough lying on my back to WILD.

How do you more successful WILDers lay?
