Anyway, this is a great thread, I only wish there were more moments being described - I do understand why there aren't though; I truly think a surprisingly large number of my very best and most exciting seconds, the most euphoric and purely pleasurable instants of my life, took place on dancefloors and yet I am struggling to recall even one specific one. They have all combined in my head into one blurred image, a smear of movement and overwhelming flashing light and total pitch blackness. Pounding beats, waves of bass and the tingling of intensely beautiful melodies are layered upon each other millions of levels deep creating an utter cacophony that I cannot begin to pull apart and separate into their constituent memories.
And anyway, if I could, and I was able to describe them, then the good ones would almost all be of the form "The music was really good and loud and the lights were intense and I was high as fuck with my best friends" - the great moments just don't make for good stories.
Frustratingly though, I do feel I have had plenty of crazy and interesting moments on or adjacent to dancefloors that would bear repeating if I could just, somehow, recall them...
