Eyes flickering?

I've been experimenting witth WILDs again after taking a break and this is what tends to happen:

It'll take me about 20 minutes to fully relax and to feel the first wave of mild vibrations, and the HI will start to become a kind of blurred field before I start to almost "see" my dream. For example, the HI would start fading into a screen sort of and I'd vaguely be able to make out like the dream landscape, but as that happens, my eyes start flickering very fast, as if it's trying to resist, and eventually it will over power my will and they'll flick open, stopping the attempt. Is this normal? Any suggestions?

Um, I could be wrong about this, so forgive me, but I'm pretty sure that's what happens when you move into REM (Rapid Eye Movement) sleep.

One thing you could do to that might help is to sleep with a mask that covers your eyes. It will put a little bit of pressure on your eyes, and might stop them from opening.

Hope this helps! :)
