With some music - containing a good and somewhat more fast beat - I imagine longitudinal circles in front of me, like -on the beat of the music- the sound comes to you from above, and floats back via the bottom towards the speakers (Snap would be an example of beats I mean). When the absolute phase changes, I think this circle floats the other way around : comes from the bottom, and floats back via the ceiling.
Enigma would be another example I think (imagining snare (drum)-like sampled music with a slower attack than usual when this circle thing occurs).
Mind you, this can very well be in my mind, because it always comes to me like a "trance" thing.
Usually not being on dope.
