yea it seemed like WILD technique should work 99% of the time (sure there's false awakening too).
I've been curious to know how the entrance to lucid through SP works too.

I saw a guide that said if you open your eyes during SP and hallucinate, that means you're in a dream/deep sleep and should realize that you're dreaming. And when you close your eyes...you are INSTANTLY in a lucid dream <-- yea i was shocked on how simple it sounded lol. Can anyone explain it more, or it is really that simple xD.

But back to topic...
The only thing i took into consideration is maybe the REM cycle.
The sweet spot Lucid/dreaming occurs mostly (to be safe) REM period.
Maybe you have to SP at the right time to get lucid.
Like you could have missed the REM train and it wont come for a while xD.
