I've got quite a few experiences with salvia. It was the first psychedelic I tried, which to be fair was probably not the wisest idea. Regardless, it was the easiest (and most legal) to obtain, so I did.
I've had a lot of experience with this plant, both plain leaf and enhanced leaf, but I will only mention a few that I think exemplify my reasons for having such a relationship with the plant:
My first experience with salvia was perhaps one of the least-powerful trips I've had from it, which I chalk up to not really knowing what I was doing, as well as my anxiety. I used a torch lighter and a small pipe with a wooden bowl and metal tube. This has generally been my smoking piece of choice for salvia, so a bong/water pipe are definitely not required, but can make the smoke more tolerable. I took a hit of the 20x salvia but coughed from the intensity of it. I took a second hit and held it in until I felt it bursting out of my lungs like a bomb had gone off. I had just begun to think about that when I realized I no longer had full control over my body and my motor skills were poor. I managed to hand off the pipe and lighter to a friend before collapsing into my bed. The time between exhaling and collapsing was around ten seconds. This short period of time I like to call the "salvia buzz" period, because in my last few moments of grounded-ness, I can feel the intoxication, but I am not yet tripping. Everything just feels "weird" and my body feels disconnected from my mind. And then...nothing. I was laying on my bed, face down, and there was nothing. I was in a world of nothing. Slowly, things began to take form and everything was brightly colored pink. I could tell that I was in a room of some sort, but unaware of anything else (my body least of all). Just as I began to get my bearings and try to understand the room, the walls began to crumple up like tin foil, revealing another layer beneath them. This layer was bright yellow. Then after only a few seconds, this layer also began to crumple to reveal yet another layer, this one a very bright light blue. And the walls continued to crumple up and vanish as new layers emerged. In awe of this, I tried to reach the walls but was unable to move from my position. And then, suddenly, there were no more layers, and the nothingness returned. Confused, I lay there for a few moments before realizing that my eyes were closed and that the trip had ended. I got up slowly, still feeling the remnants of the buzz.
The second trip I had with salvia was around a year later on a fresh bit of 20x. I smoked considerably more this time and held it in longer, 2 full hits at 30 seconds each. I don't remember exhaling the second hit, only that it happened before i collapsed into the sofa. This was perhaps my strangest trip. I found myself in a two dimensional world with a pink sky and clouds in the distance. Closer, there was a farm. I could see the farm house and a brown wooden picket fence to the right side of it. Without moving, my point of view zoomed into the two dimensional cartoon-like world. I became a part of the farm, a member of the "community" there. I could remember an entire life that I had lived there, and knew everything about the other characters there. I say characters because that's what they were: one, I remember, was a pig wearing a hat. I don't remember any of the others. I only know that this world was safe and happy and a place of peace and tranquility. It was protected by a presence that could be felt at all times, even if it lacked a physical form. I remember the presence being specifically female. It felt so safe there, so perfect. And then it disappeared. I found myself back in my body, not in the position I remembered leaving it. I was sitting up. I looked at my friend who was trip-sitting, said something I don't remember, and then looked at a pillow on a chair across from me. I couldn't move my eyes away from it, and suddenly it swallowed the rest of the room. The patterns began replicating and changing and the colors became a blur of motion and distortion. I came back to my body again, very confused but feeling like the trip was subsiding. I saw my dog laying on the other side of the room and clumsily got up to go pet him. As I was petting him, suddenly the third and final trip came on. I could see my life, there was some physical representation that I knew to be my entire life. My point of view zoomed out so that it was surrounded by darkness, and suddenly as it zoomed out I could see that my whole life was just inside a box. I saw that everyone else's life was also inside a box, and there were millions of these boxes. They reminded me of boxes at a post office. Each one was filled with the person whose life it was and everything else in the box was fake. Everything and everyone in my box was fake. This didn't seem to upset me, and the only thing that crossed my mind was "I'm sad that my dog is fake". But the thought of my dog made me remember that i was sitting next to him, which helped to ground me and bring me back into my body.
Needless to say, this was an overwhelming experience and made me think for a long time on it. I decided not to try salvia again for a long time after that. Once I did, however, I felt the welcoming embrace of female presence in all of my trips. I have felt myself guided by her, shown secrets by her, and felt one with her. I have not returned to the farm, but I am sure it is the same presence. I have had many other incredible experiences with her, but those two experiences are my favorites.
Anyway, thanks for reading this massive wall of text. I hope it encourages some people to open their minds to this plant. It is certainly not for everyone and should not be treated as a quick way to "see some crazy stuff", but it has definitely given me the confidence to go on and try other mind-altering substances. It has also given me the ability to "let go", almost on cue, which has had profound effects on my meditations.
