Thanks for sharing, I'd like to add my own experience on LSD and the long-lasting effect of fear-of-death it can result in. I have taken LSD only three times and can't say I enjoyed it very much, but I still wanted to give it a chance. Last time I took a 1/2 of what was recommended for me to see how it goes, and the beginning was pretty enjoyable, I played League of Legends, and the mobs started walking on the wall behind the monitor as if the view was projected on it, it was fun. I used to smoke a lot of weed at that time, and it always had a soothing and calming effect for me - not this time.
Marijuana never caused me any panic, but at the end of the trip, I was barely feeling anything and smoked a joint, what happened next was frightening. I felt an ache at my heart and considered calling the hospital for several hours, but was scared because of intoxication. I could not relax and sit at one place, there was darkening in my eyes, and peripheral vision was gone, and LSD made the feeling of fear massively intense. It felt as if my heart was going to stop just because I was thinking so much that I was dying.
I can only name what helped me then: I started walking short distances telling myself that if I manage to go from point A to point B then I'm fine and it's just a bad drug tripped. It helped, also tasting various flavours and hearing sounds from outside the street helped me focus my attention on something else. After a few hours of walking/tasting/hearing, I noticed my heart pace slowing down and the realisation that I wasn't in any real danger followed next. A terrible feeling that I will never forget. The bad trip lasted about 6 hours, and for the next few days, I felt a sharp pain in my chest.
