Here's a copy/paste from another forum where I started a thread about my "theory" on my experience with Salvia:
" Okay. Well, beingone that has experienced the "layers/slices of reality" trip every single time I've smoked salvia, I've been very curious as to why it is that I've had the same trip repeatedly. It's been almost a month since the last time I've had the trip (stopped smoking to wait and see if I could remember it with time). It turns out, I remembered enough to come to quite a reasonably hypothesis.
People that experience a variant of "layers/slices" trips experience layers of what they perceive to be "reality", stacking on top of one another. They may see ahead of them, outlines or images of themselves reacting to things they haven't felt yet. But, sure enough, they fit the outline/image.
When your eye sends an image to your brain, the image combined with your nervous system stimulate your brain to perceive this one split-second of "reality" or 3d space. I believe that Salvia slows down this process. I think that the images and nervous messages sent to your brain stimulate your brain, and stimulate it for longer than it is supposed to. Normally, perhaps, an image and nervous message would be sent to your brain, and it would be immediately replaced with another image and sense of space. Well, I think that salvia causes the images and feelings to sort of "stick" in the brain. Hang back longer than they're meant to. Resulting in multiple messages stimulating the brain at once. This means that a person would experience multiple 3d spaces at once. This would mean that the user was experiencing 4 dimensions.
The closest comparison I can make is to an old projector. The ones that had a wheel in which you'd place images. Let's say that the images were, instead, instances of 3d space. The images placed in the slide were an image and feelings sent to your brain. Normally [sober], one would perceive one of these 3d spaces at any point in time. However, being on salvia would be the equivalent of widening the range of the amount of images that were projected at the same time.
Using an arbitrary number of 5, let's say that the brain perceived 5 images and feelings at once, rather than 1 [sober]. As the wheel scrolled, one new image would appear, one old image would move from your sight range, and the images that didn't disappear would move back a slot. That is what the user experiences when they move and change their field of view, resulting in more messages being sent to their brain. To people on this trip [or, at least me], it would look like reality, perhaps, stacked on top of itself, or rested vertically on each other.
That is the best I can describe my trip, and come up with reasonable explanations. Tell me what you think. Perhaps it's not as possible as I think.

Another post of mine from another thread:

"At about 1AM this morning, I smoked half a bowl of marijuana, and then set the mood for a bowl of 15x. I hit it. One hit. And it hit me back twice as hard. Everything suddenly stopped. Paused. And after a few seconds, the next frame of what happened was revealed to me. Slowly, frame-by-frame, reality was shown to me. It was as if everything that happens is cut into really long thin slices, and dropped in to place. I thought that I was stupid for thinking my life was real. It felt as if everything that happened forever, and that was still happening, was totally pre-set, and that forever, there were slices of reality just waiting to be dropped. The slices fell faster and faster, and I was becoming aware of what I was doing. I got angry, and wondered why I was here. After a few seconds (8 minutes), I remembered that I exist, and that I had smoked salvia, and simply sat there, trying to comprehend what I just witnessed."
