Crazy Eyes

Since yesterday I've been insanely scouring the Internet looking for answers on a particular experience I had during yesterday's AP attempt. I've had no success on finding a clear answer, I wasn't sure about asking here, but I'm pretty desperate for information. Or even to know that someone else has experienced this. I was attempting AP, experienced all of my usual cues of AP coming. Sleep paralysis, falling feeling, rapid heart beat, etc. But this time as I shifted my eyes up to focus on my third eye my eyelids began fluttering uncontrollably. I wasn't exactly freaked out but this but definitely taken aback. I tried to keep my eyes closed worried I'd be thrown off track by this crazy eyelid fluttering, but I just couldn't seem to keep them controlled. I don't know what was happening. I'm kinda concerned. Has anyone else experienced this? Or does anyone know what this was? I know surely there is someone here who wouldn't mind lending their knowledge/expertise to a newbie. I'd be very grateful if someone could help out. Thank you ; )
