Hello, two days ago i found out people had these things called lucid dreams, i dream a lot, but i dont remember being lucid in any of the dreams.
I tried my second WILD today and i failed, maybe becouse it was an afternoon nap and i couldn't sleep, but i have some questions regarding WILD.

1- I know you have to keep your eyes closed and your body still at all times, does that include the tongue and lungs? sometimes i slightly move my tonge by accident, and for the lungs there is no much to do about it right?

2- in this afternoon WILD session i experienced some strange stuff, first, after sn hour being perfectly still and my eyes closed a feeling came down to me, like it was a chill, from the top of my head to my feat, and my leg muscles were tense, does that mean i was in SP?

3- during my sessions i started to have "micro-dreams" like i was actually dreaming for half-a-second, i quickly wake up with my eyes still closed, this happened to me like 5 times that session, is it normal?

4- how do you enter the "dream world" using WILD, i know its from those allucinations, but is there a concrete way of doing it? Is there like a sign that you know you are about to star LDing?

Thank you guys
