now i know i know nothin but that sounds like you're activating your third eye. thats the first thought i had when you said you aim your eyes upward.
brush it off as merely hallucinations and chemicals being released... or something more. cause DMT is released from your... oh quiet!... there is no third eye.
G'night, Mydriasis.
edit: i decided to smoke and chill then sleep. i hadn't once day... but after posting felt like good time to smoke.
and also i think only you can figure this out, and it'll be great so you can relax.
other people here have to know something besides oh you just had a hallucination or whatever ya know man. hahaha
