yeah that thing has happened to me before. its basically the reason i dont really smoke pot anymore. me and my friend were smoking some good shit he got. well were smoking and i had the same mindset i always have while smoking(so i know it was not a mental thing), well before i knew it i was baked like a mother fucker. i mean we got out of my friends car and i couldnt even stand still and i couldnt stop shaking. we go inside his house and i try to watch tv, For 30 minutes straight my vision would go from clear to fuzzy every 3- 5 seconds. i really felt like i was dying. it wasnt a good experience at all.

Then i had some more bad experiences a couple months later like super sensitive hearing, feeling numb, dizzy etc. but i remembered how i busted my head a week before and realized i had a concusion. (Do not ever smoke pot after a head injury)

I can understand all the bad experiences i had while having a concusion but i still dont get what went wrong that one day when i felt like i was dying.
