I've done a series of them:

Salvia (50x extract): Way too powerful and intense, not fun. I thought I was an alien posing as a human and my skin/costume was falling apart and I had to keep my shit together or else people were going to stone me to death. Also, I grew extra arms out of my shoulders and they were trying to take my hat... but I wasn't wearing one :-( Another time, I kept imagining an orange comet crashing into a blue sea, over and over and I couldn't understand why I kept seeing this shit, but it turns out it was just me trying to pass an orange pipe to the next guy but he didn't have enough depth perception to accept the pass and I was too far gone to compensate.

Acid: Multiple times, most fun for me, reached various insights, became less depressed, learned to appreciate people (I never randomly chatted with people before acid, now I can small talk and crack jokes and make people I never met before laugh and smile, and in the process, I as well). I never realized the social need and aspect of my person until acid. Visually, it was exciting, colors, patterns, things coming together, really amazing. The first time I did acid, I was like, this shit doesn't work and I peaced out and drove home and that shit turned into Mario Kart partway through. I pulled over for a break once I realized I was having too much fun driving and pulled into a starbucks where everything (the walls, tables, etc.) was breathing in time with me. Met up with some coworkers there and we had a lot of fun just talking, or at least, I did, haha.

Acid+Weed: Much more mellow, used Purple Skywalker that time, easy to enjoy trip, helped me get out of the headspace and more into the funspace.

Acid+Nitrous: Turns up the acid trip to 11 for a minute, really intense, cartoony visuals.

Mushrooms: Kicked my ass the first time, we were out in the desert at a rave and I bought mushrooms and had no idea what to expect, none! I ate the whole thing and fuuu, colors were intense, couldn't stop smiling and enjoyed myself immensely, afterwards, I locked myself in the car and hid the keys so I wouldn't be tempted to drive. I imagined demons and they had chains made of raver beads and there was a wall of human flesh and the demon wailed on the mound of flesh and limbs and it screamed a frightening howl! It kept whipping it and whipping at it and then beads and flesh broke off and then puddles of blood and raver beads turned into actual ravers and I was back at the party! It turns out the screaming was just dubstep. It was a trip.

Acid+Mushrooms I met spirits and gods and shit and felt like I was disconnected from reality but still participating.

Acid+Mushrooms+ectasy: too much fun to be had that night, oh man, I was on another level!

DMT: I was doing acid and mushrooms and in combinations in order to build up the tolerance to handle DMT, but it was nothing in common. DMT is literally the hardest you can trip/hallucinate, there is nothing higher (that I know of at least), I hit the pipe and then I had to lay down in the grass and the last thing I saw in reality was the smoke leaving my lips floating up to the blue sky and then suddenly the universe came up and swallowed the sky and the smoke and myself. I was floating out in space for what felt like years, watching the stars move, but then I realized everything wasn't moving in 1 direction, everything was moving in all directions but coming towards me. I wasn't traveling through space, I was traveling through time! the universe was becoming smaller and smaller and then I witnessed the bigbang. That is like, a whole other post honestly, that experience was truly something else, the only thing that has ever come close to it was:

Acid+Adderall: I railed adderall after I took acid and my god it was like walking in a DMT dream for hours and hours, intense trip, the colors, the shapes, I felt I saw and met the essence of beauty.
