Hey a1112,
I have been WILDing/trying to at least, for about a month now and get very similar symptoms to you.

I lay down, relax, and meditate/focus on pressure points - I find focusing on pressure points a great way to calm myself.
Then I get numb.
Then I start getting some brief HI images.
Then I get a weird light that looks like I'm moving really fast over train tracks and behind the wooden slats is white light which shines through my dark field of view.
Then I either get really tingly and slight vibrations OR my eyes twitch like you discribed. It starts out minor twitches but gets to the point that they are screwing themselves up of their own accord and my eyes start to water.
Never really get beyond this point, but all these first steps are easy for me, I can do it all in 10-30 minutes of laying down.

I was told that battling through the eye twitching is probably the best way to go but it gets to the point where it almost hurts and is really annoying. I'm quite sure they are my real eyes doing it too because under them is wet when I wake up.

I'll keep an eye on this thread too

Cheers
