Yeah, you had a bad reaction all right. Salvia is not one of the most pleasant drugs. I've laughed from it a few times, but mostly it was just uncomfortable. The pain that isn't pain.
It's funny though, salvia will take me to a similar place DXM and cannabis/JWH-018 do. With salvia the trip is totally immersive, but confusing. With the others, I get a feeling of the place. It's always positioned to my left for some reason. It's a place where I can see my memory as an array of banks. Some are empty, waiting to be filled. When I'm experiencing it, it's like I'm close up to the whole community, like I'm interacting with the global unconscious mind.
I tried the quid method once, and it was much more tolerable. More enlightening and clear.
