Only one I can remember is I was on mushrooms and my mother came round to change the curtains - I was unable to stop laughing so she said "What are you bloody laughing at"
My third time eating mushrooms, me and two friends were visiting for Christmas, during our first year of college. Well, one of the friends was our friend from high school who was still in high school. We decided to take them in my parents' attic, which was our traditional hangout spot. It's an awesome attic, like the one in Neverending Story, super tall domed ceiling and massive, lots of good memories. My friend brought the mushrooms, he had a quarter pound he was selling, and some weed. We had a bunch of CDs, snacks, and we made a pact that we would not leave the attic for any reason, so we'd be safe and not encounter my family.
We got impatient waiting for my family to go to bed, so we went up there while they were still awake, and ate an eighth each. We started coming up pretty hard, and our high school friend started getting weird. He was being really loud and aggressive and egotistical, he kept saying "these mushrooms are bullshit, I don't feel anything", except he was clearly fucked up. Me and my other friend were getting anxious because he was being so loud, and he was calling us pussies and bitches and talking about how strong his mind was because mushrooms couldn't even affect him. It was his first time ever tripping, and my other friend and I had done them twice together at college and had great experiences.
Anyway, after probably only like 20 minutes, our friend who was being a weird asshole started bullying us to go downstairs, he said he wanted to go outside because he was bored by our "gay music" (it was Radiohead's Kid A we put on first, which in retrospect was probably not the best choice, that shit's dark). He was insisting that it had been long enough and my family would definitely be asleep and if they weren't, he didn't care and it would be fine. Then he said he was going, whether we were or not. I was terrified by the thought of him going down there and seeing my family and getting all weird on them like he was on us. So we all went down, me and my normal friend feeling increasingly full of fear.
Well, sure enough, we walked downstairs and the whole family was up, watching TV together... it was only like 8:45 or some shit, lol. My mom was looking at us weird, or so I thought. I was fully in the fear now, I felt sure they all knew and were disgusted with me. The asshole friend was talking all loud and speaking in a grandiose, very strange way to them. My 10 year old little brother was playing with toys on the floor and asshole friend walked up to him and crouched down in his face and said "PHIL! Did you know that you could DIE at ANY TIME? Maybe tonight even". My little brother was super weirded out and was looking at me and my mom. My mom asked me what we were doing, she obviously knew something was off. I stubled my words really badly but told her we were just getting snacks, which we did and ran back upstairs.
So at this point, me and my normal friend are just massively anxious, stuck in the "oh god, what have I done, I wish this would stop" loop. Meanwhile, our asshole friend was getting increasingly aggressive and mean to us, kept laughing at us and calling us pussies, saying that mushrooms were for pussies and ecstasy was a real man's drug, shit like that. It just sucked... full stop. Bad time.
Then we heard my family all go to bed, and we all wanted to go outside, so we went down, and went outside, but felt like we needed an excuse, so I took the dog out with us, and it was cold so I wrapped the blanket from the couch over my shoulders. We started walking down the block, smoking cigarettes. Me and normal friend were still anxious and filled with fear, and asshole friend was shouting stuff like "I'M KING OF THE WORLD!!" and "God damn you guys, I'm the smartest person in the world, I think! I'm so much better than everybody else I know!", and he was like laying down in the middle of the road and laughing like a maniac. So obviously this was not helping because all me and my other friend could think about was, what if a cop drives by? What if a neighbor calls the cops on this asshole? Some cars were driving by from time to time, and I was hallucinating cop lights on every one, I was SURE I could really see them, one time I even hallucinated the red and blue flashing lights.
So after a bit, we convinced asshole friend to come back inside with us. Then as I walked in the front door, I hear "Hello, XORKOTH" (except my real name). It was my mom, hiding in the shadows. She scolded me for making her dog and blanket smell like smoke, and I guess we also left the front door wide open and the cat could have gotten out. And she said she knew we were on something. And then, she said "I went up in the attic, and I SAW what Brandon (my normal friend) has in his bag. How dare you bring drugs into my house? I'm throwing it away.
Well, we all thought she must have meant the quarter pound of mushrooms, of course. Turns out she meant his little pipe and tiny bug of weed. Somehow she must have just not knwon what the mushrooms were, because the weed was wrapped in the giant bag of mushrooms.
Anyway, it was over for me then. I went into full bad trip mode, the rest of the night, we all just sat in chairs in the dark, without saying one single word to each other. I was stuck in a loop of self-disgust, guilt, and fear. Similar for my normal friend, and our asshole friend said he was just bored and didn't want my mom to get back up.
Then, as soon as dawn began, we all came down all at once, and were flooded with the most profound feeling of relief and gratitude for feeling normal again. We had survived! We went up to my room and started talking about the experience, laughing, smiling, expressing how much we appreciated being sober and that we had been afraid it would never end.
Despite the really difficult trip, I had an amazing afterglow for days afterwards. My mom never said a word about it the next day and my friend found his weed in the trash and took it back. Many years later, I talked to my mom about it, and we laughed about it.
