Goa and psy have the power to make me happy, give off good vibes or make me feel totally awesome.
It often gives me the "train"-feeling, as if the music were a locomotive, taking me places or just moving forward, through an everchanging soundscape.
I don't really "see" anything when I listen to the music, It does make me think about a lot of things though, like hyperspeed spacetravel, ancient shamanistic dancing rituals or really huge factories with pumping machines.
The complexity and absolute awesomeness, the "alien" feel and the sound is sometimes so spot on, it's actually hard to believe. Never has any kind of music given me the postive energy and euphoria good psy/goa gives me.
