I've done salvia twice, both times it was 5x extract smoked out of a dry bong, the first time I believe it was 1/15 g leaves, the second time was 1/10 g.
The first time I did not get a breakthrough, just a feeling that lasted about 30 seconds. I was laying on a bed but it felt like I was laying on a wooden picnic table and getting sucked down through the cracks. Then I got the impression that I was being swept up in a bag of dry leaves or something, swinging back and forth on some journey to an unknown destination...but all dark, no visuals at all, and it went away after a few seconds. Salvia users tend to scale things as follows:
S --slight to no effect
A --altered perceptions (maybe closed eye visuals, but mostly just weird impressions of things)
L --light visionary (CEVs, definite altered perceptions and hallucinations)
V --Visionary (CEVs, OEVs, complex hallucinations)
I --intense visionary experience (i.e., visiting another planet)
A --amnesia, don't remember shit
This first trip I ranked as an S-A.
The second time was more intense and took effect almost immediately after I took my second and final hit (I was already tripping by the time I changed from a sitting to a lying position). Someone in the room made some comment (don't remember what he said), but the words started to echo as the trip started, like a broken record almost (ever been caught in a loop? You know what I mean), and the room started to spin in a jerky sort of manner, like a washing machine almost, back and forth, in exactly the same rhythm as the sound echoing. Synsethesia started right in...the sound echo *became* part of the room.
By the time my head hit the pillow, my body and everything around it felt like it was being flattened, folded at a right angle, and then flattened again. My body got flattened into the bed, folded into a right angle, and then flattened into the wall, which got folded and flattened into a copy of Van Gogh's "Starry Night" on the wall. It kept folding and flattening until I found myself somewhere else--the only way I could describe it as a dimension that exists at a right angle to ours.
I wasn't human anymore; I was a tile floor. At least my body was. For some reason during this entire trip my head stayed round and not flattened or folded into anything. Go figure. But anyway, I was a white tile floor in a grocery store--it was a grocery store near my house that my mother used to take me to when I was very little.
I was nervous at first--my first acid trip was a bad one and I've always been super-alert since then for possible weirdities that could spin me into another one. But then things started to make sense, and I started to speak...jerkily, because everything was still moving at that annoying broken-record pace:
"Oh--I--see--everything--is--connected--to--everything--else...that's--all, really--there's--nothing--else--here...it's--not--bad, just--strange..."
...or something like that. That was when I felt the presence...lady Salvia, I'm sure of it, although she wasn't nearly the entity I expected she would be. I still don't remember if I ever saw her face, whether she was someone in the store I was the tile floor for, or if she was just in my head...but I got the impression that there was a female presence near me. She felt distinctly like someone who might have been a friend of my mother's when I was about six years old, some figure of authority who I didn't really know but may have babysat me a few times...not unpleasant, just not particularly familiar either. I also am not certain, but I believe she was the presence that set my fears at ease, because she seemed to be smiling as I began my journey back to the real world (tm), folding and flattening in reverse until I was back on the bed again. The entire experience lasted about 5 minutes.
I ranked it later as a V--I'm told that my eyes were open the entire time, so they must have been open-eye visuals, but like some others I didn't get any spiritual benefit out of the trip (and this coming from someone who gets religious experiences off of a gram of shrooms every time). The whole thing just seemed absurd, weird, and just a little boring and devoid of real meaning. Yeah, I guess some people would be pretty excited about being turned into a tile floor, but it wasn't all that great, trust me. Turned me off of salvia for the time being. I'll try it again one day, of course, but the message I seemed to receive from the grocery-store-floor episode just seemed to be lady Salvia telling me that although I didn't do anything wrong, that I didn't need to be delving into this drug just yet.
