Had a similar experience with acid. First trip too. Saw myself from an outside perspective and realised I was a horrible person. I was going to jump out of the window but i didnt want to make to cause anyone anymore pain. My friend offered me xans but it took my 10 mins to say no cuz i was tripping so hard. I also made the mistake of smoking weed thinking the acid waasnt working because i was 5 hours into the trip and nothing was happening. Had to stop smoking weed on a weekly basis afterwards. i have really strong dejavu. I wake up from sleep with memory of a strange dream. Then when i smoke and the following days after i experience those same dreams in real life. I smoke weed around once a month now and it still happens. Ive gone months before without weed because the high is so crazy i just get sick of it. Every noise made turns into music and loops over and over again until it fades away and is replaced with real intruments. Its like a radio in my head. I also always get paranoid now. I think way too much and watch everyone closely and over think. The only thing i do now is alcohol at parties because for some reason i handle it well. Even then ever since the bad trip I dont even want to get drunk. I just take a couple shots and play along.
