Why do u guys think happend?

we'll the first time i smoked i bought a gram of sweet smelling skunk and i roll a joint so me and my sister go on the balcony to smoke it so i take about 8 hits **** takes i forgot how many hits so i go back inside and i got chill in my room and all of a sudden it hits me and for some reason i couldn't think, like i couldn't think straight so i knock on me sis's bed room door and all of a sudden everywhere i looks it would glich and move all glichey so im freaking out and my sis is laughing and saying "chill out your just very baked" and i keep seeing pitch black every time i blank out and this lasts about 3 hours and then i go outside and the air feels wearied like rubbery was it laced?
