I'm happy to see someone with a positive attitude towards salvia and vice versa. The main reason why I'm eager to try DMT is it's relationship with music that I'm loving so much: psychedelic trance. I'm looking for both visual and philosophical inspiration when approaching art. Salvia experience is mostly beautiful and only once I had bad experience when I was throwing pillows at my former girlfriend.
[Explanation or rationalisation: I was mad and irritated. It was a bad time in my life and I was "tested positive" for having a quite strong astral parasite. Still, it turned out that this girl was seriously unstable emotionally and it was very painful and psychically draining relationship. In certain situations I still dream about her but I'm happy that it's over. I think that MAYBE salvia showed something about this girl and that's the reason why I had aggressive behaviour aimed at her.]
Other then that, I've never experienced anything unsettling. When I smoke salvia alone I always lay down. I never stand up and move around. I feel perfectly safe when I enter the salvia-space. The problem is that I must force myself to smoke it. But I love salvia's visual side. I love her visions and messages that I'm receiving. The afterglow is beautiful and I find high therapeutic effects when I'm in a bad mood. Plus, it keeps going for a day or two. Salvia seems very euphoric to me. Sorry for this off-topic but I felt obligated to defend this plant. It is really magical. I place her over LSD and mushrooms but I'm not sure about ergine or mescaline. Both latter substances are very healing.
That's why I'm looking forward to trying Changa. I've heard lots of good information about it. I know that it originated in Australia, probably inside psychedelic trance circles. DMT seems to be more fractal, mechanical, colourful and cybernetic. It would fit psytrance ideally. But I want it to be at least as powerful as salvia, especially that I'm not into trying salvia any more. It's an advantage over other drugs because it doesn't steal your mind and soul. You just don't treat it as a drug. All who do so have bad experiences.
Sorry for a bit long post, maybe too much off-topic.
