Sorry for the double post but people who read email and then respond sometimes don't see edits.

What you described is you wanted to proform the WILD technique but I think in your reading you missed WILD is When you froze you were in sleep paralysis which is a part of the WILD. And you also don't need to WILD to have lucid dreams. You can do DILD, MILD, other wild technques like, FILD, VILD, SD-WILD. Or WBTB which you can do after naturaly waking up.
