Well, there was this guy who had a scary weed trip. He was in a room with his friends, but during the trip, he felt like the walls were closing in on him. It got so bad that he ran outside, thinking he could escape, but then he started seeing strange patterns in the sky that made him think the world was ending. His friends had to calm him down for hours.
One scary weed trip story I heard was from a friend. He smoked way too much and started feeling like he was being chased by invisible creatures. He couldn't shake the feeling of dread and was constantly looking over his shoulder. Another person said they had a trip where time seemed to stop and they felt completely detached from reality, which was terrifying as they didn't know if they'd ever come back to normal.
I know of a story where someone had a bad weed trip. They took a strong strain and suddenly became extremely paranoid. They thought everyone around them was plotting against them. They locked themselves in a bathroom, fearing for their safety. It took a long time for the effects to wear off, and it was a very traumatizing experience for them. Since then, they've stayed away from weed.
