thats nuts
my first two experiences were similar to what you both have to say
weird, fun, lengthy in explanation
that ALL changed the day i went off the deep end.
3rd time tripping on salvia, i took a huge hit of 30x, exhale, the last thought i can sensibly communicate was "fuck i exhaled way too soon, what a waste of salvia" i could not have been more wrong.

people have explained their trips to me where there is some reality, like your coffee table for example.
there is nothing to ground me where i went, its similar to your trip in the 2d sense, but like i said the world around me was gone, i was alone, i WAS the 2d shape and i was folding for ever and ever outwardly spiraling. like my conscious interpretation was the only thing in existence.
my first two trips, yeah some what sensible, perhaps enlightening.
this: FUCKING HORRIFIC. much like in the picture you posted i felt my body squeeze like play doh for ever piling and folding on top of its self. i had no bearing on what my actually body could be. i could hear all my friends distantly within the folds, sound was stretching around me in a similar fashion to the rest of the world, but i was in the middle of it all so i couldnt see or hear one specific moment, it all came in one fucked up smear.

imagine everything youre experiencing right now is a blanket. all the sounds, sights, smells, feelings, are flat. theyre as comparable as a square to a triangle. they are both from the same dimension they just differ in shape within this realm. now we take our sights, lay a triangular piece here, sounds, lay a square piece there, until we have a blanket. picture you lay on one end and start wrapping yourself in it. eventually you reach the blankets end, or the wall of the room youre in, on salvia its infinite. you can move, but its as unchangeable as time. i could roll/fold more or less, but i would still be in the same place, no where, salvialand.

i started to freak out so i tried to stop the folding and rolling, bad idea. i could hear all my friend laughing from forever away, saying i was stuck there, in the middle of a moment, then the director of time (im not real religious) got pissed off at me, fixed the folds, and sent me on my way.

when i came back, i was almost in tears. i couldnt make sentences (not even in my head). all i could say is fuck, bad, horrible, and other words or fragments of. i thought i would never be the same, i couldnt even remember who i was, i knew my name, but not my character. i knew i liked music and poetry and drugs, but i couldnt justify why. i was like a text book of a human being. passionless.

when walked up to the bus stop i saw i had about ten minutes to kill. i glance at my i pod and almost immediately the bus appears front of me. i check the clock again and sure enough ten minutes had passed. time had no sense. the lack of reality now that i was back scared me even more than the trip itself. atleast then i knew i was on salvia. right now im supposed to be normal, i want it more than anything but i just cant have it. after about an hour of riding the bus, an hour in blackness under my sheets. i was human again. i wrote a poem, and inspired to better understand quantum mechanics, sacred geometry, religion, life, and death.

i cant say it was a bad experience, because of it i learned a lot. it didnt hurt me in any physical way.

getting hit by a car, that sucked, not something id recommend. i think salvia is in the same category as that. yes its something to experience, car crashes are exciting to talk about, but not to be in. it isnt as though youll break any bones or loose your life, but you may stop believing in both.

I have one burning desire though ....i want to truly understand where it is i go to and how it is created ... something that seemes completely impossible whilst in the stupor of such a deep salvia high and even more impossible when back in

Salvia is definitely a wonder. My first experience with it was 40x, and it was about a half of a gram out of a bong. Almost instantly I felt as if I was removed from my body, and brought to another world looking down from the sky at an assembly line with copies of myself going down the line. When I was brought back to this reality I felt as if I had to pull myself out of the bed surrounding me, and the two friends that were there babysitting said that I tried running while under, so they had to hold me on the bed for a minute.
