I was practing projecting...and im listening to the track "Concious-Exit OBE Practice" (the second track..its the 17:06 minutes long one)...

and im layin on my body...and i noticed that i can hear like... a sound that goes as fast as my vibrations...if my vibrations are slow..then this specific sound is that slow...i turned over on my stomach...and i put my hand on my stomach. so i was pretty much layin on my hand. and i could here that little sound..and i felt vibrations...like my energy hand felt the energy vibrations...and the sound coming from my head phone was as fast as the vibrations that i could feel on my hand. like...its not the actualy frequency sound that comes from the track...but a sound in the background...idk how to describe it.

it's just something i noticed..i thought it was interesting.
