Having a chill song makes a lot of sense since dmt puts you in a very deep natural meditative state (kind of) and well. . . so I guess meditative music would enhance the process! And as for the other comment, that also makes a lot of sense. . . and since I believe true meditation is the happiest state of internal being one can be in, I guess any song that naturally eases you into a meditative state would help
Also, what's better, low light or higher light conditions? I'm guessing lower light but I haven't tried it yet. My first aya experience was WAAAAAAAAAAYYYYYYYYYYY too intense with a huge fire burining in front of me!
