For literally years, I wanted to make something scary sounding and ambient, but my mind made excuses not to try. Well no more, in one hour I doodled this noise/sound using only a few tools and my Mac's microphone. Some sounds are sampled and played backward from the Beatles' Revolution #9 song.
Anyway, hope y'all enjoy, my intention was to explore and play with sound, and make scaryness out of sounds that are not normally scary. :3

For best listening, use headphones or powerful speakers in a very quiet room, preferably with almost no light. This is a very quiet sound, so adjust volume to your comfort, but not too loud.
I could tell you how these sounds were created, but that would ruin the mystery, and the eerie noise...
