I am 24. Last night i was drinking alcohol and did smoke up with my friends. I don't do it usually, only on occasions. I slept in the night for 2 hours only. When i woke up i was normal but suddenly i felt dizzy and i fainted with my eyes wide open. My eyes were open i was biting my tongue it was bleeding in my mouth because of it. My boyfriend threw water on my face and then i scared. I don't remember what i said , what have i done even after waking up. It was a frit or seizure attack kind a thing. But I don't know the reason. It happened before one time. That was scary too because that time it felt like i am dying and i am controlling myself to not to die. What is this?
