Psy trance has never reminded me of summer or the sun.
For the first 5 years I was into psy, it was usually accompanied with lsd or mushrooms, dark forests, abandoned cottages, caves, sitting beside lakes in the moonlight, that sort of thing. As a result psy music usually reminds me of the night, of mythical beings, of space, of time, of extreme horrors and extreme beauties, of the depths of imagination. Definately not summer.
