Is it normal to trip of weed?

i was at my boyfriends friends house, we decide to smoke out of the bong, i got greens. i didn’t get any normal hit so i sucked up what little smoke was in the bong still.. wrong move, it went down the wrong way.. bad move again i started coughing uncontrollably.. i got up to go get air thinking that would make the coughing go away.. i put my hands over my head to let air in, during all this i was still coughing.. i sat down lied down nothing helped spent good straight five minutes coughing.. then i got up. thats when it started. my head started spinning i sat down, friend brought me water i drank a sip put it down and felt worse, decided ok this is not normal i need to get up, got up and blacked out and caught myself on the way down, got on a bed sat up and then the hallucinations started. i started staring into nothing, my friends were around me but i couldn’t understand anything, i saw squiggly lines, everything at some point was repeating. Also i couldn’t understand where i was what they were saying everything they said seemed to connect to the next word they were saying but not in a way i could understand. i felt as tho it was going to stay that way forever. i felt retarded. like the actual retarded, i thought i was going crazy. i felt like i was dying, i thought i was talking but after my boyfriend said i wasn’t saying a word. i was seeing things repeat, i was seeing things skip, i kept blacking out, i had no perception of time, or anything. it was like i had gone to another world, i was in another state of mind, i wasn’t myself and nothing was it self, if they didn’t calm me down by telling me everything was fine then i would have lost it, what got me back to normal was the whole time i was tripping was trying to concentrate on what they were saying, which was hard cause i didn’t understand, the second i actually got it i got up and i understood i was trapped, but it didn’t go away instantly. it took about an hour and after i ate it was gone and i was back to myself….i was gone and it was horrible. btw i am a normal smoker not every day but on times where i can get it, so basically I'm not new and i know how it should feel. and this felt wrong.
