Your comment really resonates with me and wholeheartedly mirrors my own experiences with psychedelics. Of the lysergamides, I've taken LSD, 1P-LSD, LSA, AL-LAD, and my favorite: ALD-52--IMHO, the Cadillac of psychedelic drugs. It's a close analog of LSD with fewer "body load" effects, almost zero nausea, and a less scatterbrained headspace--sparkling clear with beautiful visuals and an uncanny tool for productive introspection.
Set has so much to do with the experience--though I've had fun with it out with friends at a bar in dark of winter, its true power is sorely wasted unless I'm in nature, especially when my wife and I are taking it together.
I know with zero uncertainty that it acts as almost a forceful, powerful therapy with even a modest amount of mental input--it's as if your brain is forced into a state of deep meditation where you can't help but improve your mental station (barring the notably rare "bad trip"--though I've taken it with so many people, I do believe it happens less frequently with ALD-52 on account of its mental clarity).
Some of the best days of my life have been while tripping on ALD-52, wandering wild goat trails, exploring the vibrant innards of canyons, weaving among mountain pines.
RE your experiences with water, I've had the same experiences. One of the most memorable moments of my life was returning from a short high desert hike, to sink to the bottom of a salt water pool, look skyward, and watch the desert sun dance and play with colors on the water's surface. I've never looked at water the same since. I'm cheerfully captivated with its beauty in a way I probably haven't since I was a child.
Which brings me to my final observation. The effects of psychedelics, perhaps owning to their serotonergic effects or their disabling of the default mode network re-imbue you with a wonder in the world around you that has slowly, inconspicuously eroded little-by-ever-so-little each year into adulthood. Year by year, the world becomes more bland, less exciting, less, well, full of wonder. Remember those magical memories of childhood? Perhaps running towards the ocean, arriving at summer camp, having a picnic in the park, diving to the bottom of the pool, playing with a new toy on Christmas, the excited anticipation before a sleepover, your first crush? The magnitude of those feelings are often so muted or jaded as an adult. The right psychedelics can bring those feelings rushing back, unfettered, unadulterated, pure. Suddenly you realize how much of that you've lost, while simultaneously getting to feel them again in full force. Some of that stays with you during sober times, which is lovely. Dosing periodically keeps that magic alive in you--what a joy, a gift.
Humans have taken psychedelics as part of daily lives for tens (if not hundreds) of thousands of years. The shaman is little more than an elder trip-sitter and therapist. Our highly complex brains have evolved alongside such chemicals and experiences to help define meaning and seek happiness and it's a crying shame that waves of prohibition have stifled that nigh fundamental human experience. It makes me happy to watch that damage slowly be undone with news like this.
