diphenhydramine causes shit to appear from nothing but I would not recommend it at all as it stems from delirium. Ketamine has also caused vague objects to appear from nowhere but my imagination, like shadows in windows etc
Yup. The only time I was convinced my hallucinations were real. Ran outside because I saw a rhino. Walls were covered with spider webs that floated an inch away from the wall. They would even move when touched. Was not a good time. Big difference in being delirious and being on a psychedelic.
