Let's see...
Hmm... I can't really just narrow it down to one, there are a few compounds and combinations I've done which all were mindblowing in their own right.
In terms of sheer visual immersion, a salvia breakthrough is easily the most intensely visual experience I've ever had. The problem is... "I" wasn't there to really enjoy it, so I appreciate the "less hardcore" visuals which are still based in the real world - like LSD, DPT, mushrooms, etc. But anyway...
For me personally LSD is hands down the most amazing experience I've ever had visually speaking. Not to mention the mental aspect, but I don't want to digress. LSD's visuals never fail to amaze me because I can, for example LITERALLY get like an inch away from the wall or whatever I'm staring at, the the quality of the visual never loses any resolution whatsoever, like it's really there. On roughly 300mcg I decided to go into a closet to be in "pure darkness" to see what would happen since my world was already a sea of colors, shapes and neon streamers. All I can say is... w-o-w. Absolute darkness is simply stunning..
DPT would be my second preference in visuals, which are very similar to LSD but the ride on this tryptamine is much rougher coming up to the peak, it feels sort of like a hard acid trip, and you go from sober to about 30-40 minutes peaking, an hour or so of plateau, wears off within 2 hours leaving a great afterglow. On DPT I've snorted 80mg with a friend of mine, and walked out into the city of Chicago right near wrigley field. It was so intense that we just sat down against a busstop and obersved the alien world of pedestrians, convenience stores and the sound of buses gliding by. The air in front of me was filled with neon whisps, forming constantly into beautiful shapes and patterns. The world was truly a brilliant site to behold. After a minute or two of this, the "smoky neon color whisps" (we were smoking cigarettes) materialized into a Jester wearing a tophat, with playing cards stuck in the brim... it was completely unreal. He reached out his hand to me, grinned, and then vanished. Needless to say, DPT is pretty damn sweet.
Next to that I'd say high dose shrooms. I had tripped maybe 30-35 times on dosages of 2-4 grams typically, and never really had a mindblowingly visual trip. To the contrary, I barely ever got any visuals worth mentioning... until about a year ago. I consumed 5g of
extremely potent cubensis and experienced complete ego annihilation and visual disconnection from this world for about 4-5 hours. Never did I imagine shrooms had such power... man they can really blow you apart.
Anyway I'm late to class and this adderall's probably fueled most of this post.... lol
