Alright I got a few short experiences with salvia to share
Me and my friend had a little salvia and decided to toke it one night. We both lit up at the same time, held it in for 30 seconds, then let it out. Then my friend turned to me and said, "alright now we have to wait for it to hit." I remember thinking in response to that, that like most other substances i've tried, itll probably take a good while to come on, that itd come on slowly, and that it was stupid to just wait for it. My friend said to me in a jokingly manner, "Dude, the bench is eating me," (we were on a bench in a park). I played along laughing saying it was eating me too. My laughing then suddenly turned to frantic yelling, as the bench then actually proceeded to begin eating me (similiar to the chomping pianos in mario 64... anyone?). Out of nowhere it stretched and wrapped around me and pulled me in. I spent the rest of the trip rolling around in a 2-dimensional world, and it was scary as shit
Another trip i watched soundwaves of people's voices showering out of their mouths in the form of particles... Afterwards I fell into the ceiling and met a man up there in a train station.
Ive tried salvia quite a few times, and the first 5 were extremely scary (but also enlightening experiences)... but you kind of learn to control it or something after a few times I think... If you know what your doing, I think sometimes its best to just be completely alone, instead of having a ton of people just watching you and laughing at you, that ruins it sometimes... The trick is being completely alone, and at peace, and instead of trying to be part of the trip, just relaxing and retreating into your mind... If that makes sense..
