When i smoke freebase (50 - 60mg), i generally got this vibration, kind of "DMT rise up sounds" but way more soft and slow, in the background ; I like to "synchronise" this vibration with a tibetan bowl; for me it's a sign the effect is coming, i just have to catch the train, jump into meditation-vision state. This sound last mostly the first 10-15 minuts

Sometimes this white noise will transform into music - whole beautiful pieces blossoming out of my mind. A white noise contain all the frequencies, and so all the music piece possible ; with the right filters it can potentially become any piece of music
