Ok, This is not my technique to begin with but usually the FILD (finger induced lucid dream) technique is used to have a lucid dream when tapping your fingers then when falling asleep you do a RC when you feel that you are tapping your fingers.

So now you may wonder why I put this into the WILD Section, well this "Reverse technique" I call it, is very simple! Have not failed me in achieving Sleep paralysis yet.

Method:
Go to sleep and do a "WBTB" whichever REM time is best suited for you, Mine is usually from 3:00am and then again from 5:30am. If you wake up and you can slightly remember a dream then you know you just went through REM cycle "as I know it" or you can just set a alarm and work with trial and error, I just get up naturally.

Then all you do is lay on your back which is most comfortable for me when I experience SP and have the mind set to go back to sleep.

Then Start tapping your Index and middle finger very gently with no effort one after the other until you feel a lapse in consciousness, then when you realize that you can fall asleep with no effort while tapping just make sure your body is relaxed then stop the finger tapping. (as if you just fell asleep but your mind is still awake)
After you stopped you may feel Sleep paralysis hitting you instantly or it might take like 1 minute but for me it usually hits me instantly!

So my conclusion to this reverse FILD technique:
Asoon as you stop the finger tapping movement in a complete relaxed state after WBTB your mind would think that you just fell sleep because you just stopped doing that constant movement.

One more thing to keep in mind, when sleep paralysis hits you so quickly don't think (" Wow i just tricked my body into falling asleep so easily ") cuz your mind will actually pick it up and you might just ruined it for yourself" (well thats what happened to me)

This technique doesn't take much effort and I would love to hear your experiences with it.
