New with a question about WILD technique

[Acecombat007]

Hey guys, I'm glad to see this forum so active and that there's a helpful community around the concept of lucid dreaming. So here's just a little backround. I've been doing MILD lucid dreaming a lot as a kid (about 5-13). With lots of school work and crazy things I lost a lot of my dream recall (to rushed to wake up and think about what I dreamed). As of the past year or so (im 20 now) i've been writing in a dream journal and I've improved my dream recall to about 3 dreams a night, 5 or so on a good night. Anyways, my MILD techniques are okay, I recognize my dream sign about 30% of the time. (Anything trippy or odd and i bite my cheek). I watched almost everything an youtube so i know the basics. As for WILD I've been only been seriously trying this technique for about a few nights. I'm a patient person but I was wondering if this is normal. Backround: Yes I know this is bad but I try this technique mainly before I go to sleep, but I've also tried the wake and back to sleep method a couple times to no avail. And I try this technique on my back, completely still obviously, and focusing/ repeating a word in my head. I know about sounds and vibrations. So the last 2 nights I've gotten to a sound phase (sounded kind of like a helecopter+jet fighter+wind+static all at once. Not too loud, sort of like a fading in and out. Only lasted about 8 seconds. Then out of no where my eyes started to twitch (about 2 times per second) which is what i found odd. First time i gave up after 1 minute of eye twitching vibrations because it was odd. Second time i stayed with it for curiousity sake. It faded away after about 3-4 minutes. Then my body sort of went numb (especially my chest). And somebody coughed and I snapped out of it. I just wanted to check if the eye twitching is normal or if im making some fatal error here (besides prefering to perform this near bed time). Also I was wondering where/whats the best way to exit sleep paralysis, I mean I was told after the sounds get lower you can try to rolling side to side + 180 degrees roll over method.. Anyways, any tips are greatly appreciated. I'm pretty serious about this and I'm patient but I'd like to give this a try again tonight. Thanks in advance. Edit* I dont want to repost but maybe this would be better suited for the WILD technique section of the forums
