no go dark actually, everything started getting darker like i was gonna pass out. but before when i wud be buzzing out at home or something i would get everything flashing like im traveling through a wormwhole or a portal or something, silver with white and all for a few min.
I'm not sure but it sounds to me like you aren't receiving enough oxygen to a certain part of your brain. I'd reccomend smoking slower, don't smoke on a full stomach, and drink plenty of water.
Yeah, I'd try to avoid anything to aerobic while smoking. And when you're sober, some running with proper hydration might not be a bad idea. Oh, and if you feel like you're going to pass out again, do this: Immediately sit down on the ground, drop your head down and take deep breaths; breath in through your nose and out through your mouth. Do this for a minute or so after the feeling passes. I've had similar problems when weight lifting and this has always worked for me, hopefully it should help a lot.
