eye twitching/tremors on shrooms?

the other day i took prob 4-6 grams of mushrooms and the first few hours were a typical shroom trip, but at a certain point objects in front of me seemed to be glitching back and forth like it was bugging in a video game. this progressed into me seeing double like it would from alcohol, but closing one eye didn’t really help like it would if you were drunk. i could physically feel my eyeballs shaking and it didn’t hurt just felt weird and kinda sucked cause i couldn’t focus on anything. has anyone else experienced this or something similar or knows what it means? the shrooms did taste a little extra funny, but they smelled fine and had no visible mold.
