Because my mind needs to wander to fall asleep (at least I think it does, I've never fallen asleep concentrating) is it even possible for me to attempt a WILD. In the middle of last night I attempted a WILD, but even after 15 minutes of breathing in through my nouse and out through my mouth deeply while concentrating on it I couldn't get anything.

Maybe this is because it was hard as hell to get myself to concentrate for that long, and I constantly lost control of myself and found my mind wandering. But do you think it would be even possible for me to get the images or vibrations while breathing deeply and concentrating on it?
