lsd turns serious right quick

[sanity...?]

ok so SWIM, last year, came across an lsd connection.In turn, him and his dudes embarked on the mind f$%# for a good 5 weekends in a row. Thinking they should stop before it gets a little too serious, they do so for a while.
the next couple of weeks seemed ok, a little hazy and distorted at times, but everyone understood the concept of flashbacks.
So, maybe two months later, they return to the land of infinite epiphanies and breathing enviroments (on the beach).
Now, not even 3 weeks later, SWIM is having the same reoccuring thoughts , mainly, "EVERYTHING REPEATS ITSELF" was a constant re-realization and in turn got SWIM a little worried about his sanity. He became severely depressed and even thought about killing himself at times, but he couldnt figure out why he was depressed. Also, memory loss and losing train of thought were haunting him everyday. Fianlly, he figured it out, the last time they took lsd (beach), had done it, the epiphanies had made him question everything ,right down to his own existence.
he even thought that maybe humans could be cancer to a much greater being (we are destroying the world after all, and the solar system does have the resemblance of an atom, and what are we all made of? ).now im sure to alot of people that would seem rediculous, but you gotta keep in mind that acid expands the mind, making alot of farfetched theories seem very feasible, and even with that no one knows whats out there for sure. people on acid use 13% of their brain, and so do "crazy people", and "geniuses" use 12. so can it be true that acid makes you more in touch with the universe, and for alot of people they cant handle something of that magnitude? who knows.
the point in writing this thread was to: 1. help people understand how serious of a drug acid can be and hopefully forewarn those who know little about its effects but are planning on trying it, and 2. hopefully get some feedback on others that may have had simialr expeiriences.
