Hmm, that never happened to me. Never had that kind of twitch on my eyes. I had the vibrations thing 1 accidentally (i wasn't even trying to, it was an ocasional sleep paralysis situation) but doesn't seem similar to what you experienced.

Dunno if it could be related to the REM period of time, with the rapid eye movement pattern but it is strange that you were aware of it. Can't help you much tough as you seem to be in the right direction anyway. Just keep experimenting stuff. WILDs seem to be rather personal imo (you can see that by the number of different questions and answers around here). Every1 seems to have his own personal method.

Don't give up and good luck!
