It all sounds trippy and enjoyable to me as I write it now, but really, it sucked.
"It was extremely intense and strange, and I felt like I was at the edge of discovering something immensely important. In retrospect I believe I learned nothing."
I love that the "it" in this sentence could be lots of things, heart surgery, marriage, school, and even life as a whole itself.
Just a words thing
So one time they decided to ask "God" what the meaning of life was and they would write it down to study the next day. The next day all that was written down was "Walls". It felt profound but meant nothing.
That is unless walls is the answer and it is just too blunt for us to understand but that is a question for another day. ;)
People have been writing texts for thousands of years and it's obvious to me that no such word combos exist. If they did, they'd have been discovered and well-known.
So, all that was shown with the walls experiment was that experimental design was flawed. Nothing about whether the person could or could not speak to God on LSD.
I dunno, I'm not high but I can see some plausible depth here. I'm not arguing that your friend talked to god, of course, but as an answer to the meaning of life, "walls“ is pretty excellent.
Although, as a buddhist I like to think of the meaning of life as tearing down walls that never existed anywhere but our own minds. Of realizing interconnectedness. But at the same time I'm always aware that I'm not THAT far from the cringey know-it-all teenager!
Then after some time I had dengue. Well, that made COVID fever experience a walk in a well maintained park. I would not wish dengue on anyone!
The difference of these hallucinations was that it seemed so real. I got to remember what happened and a lot I can remember even now - after months. Characters, people, my connection with them, whys, whats, names, clear faces, places, signs and marks around me from those episodes. While in case regular dreams by the end of an hour so it disintegrates so fast I can barely remember I had a dream and can’t recall much of it.
