Your eyes will be closed at all times, for sure. But imagery will start to appear.

As for the position you're sleeping, i think that's ok. I get my WILD in my 2nd comfortable position. If i sleep in an uncomfortable position, i will not get a WILD. If i sleep in the most comfortable, i will sleep through WILD and miss it. So i do it on my 2nd comfortable position, which is on my side also.
