Do you hear white noise or ringing in the ears? When you are trying toastral project you need to seperate your consciousness from your physical body and reattach it to your astral body.In order to do that you need to practice meditation until your brainwaves move slow enough to reduce the energy flowing around your body in the form of an electromagnetic field so that your astral body can go through the electromagnetic field. Practice third eye awakenings, basically you focus and meditateon your 3rd eye on the forehead and visualize it opening like an eye, dont forget the back of the 3rdeye(located on back of head parallell to the the 3rd eye on your forehead). bring energy from back of eye anddo that for an houra day. Also aviod sodium flouride, it calcifies the pineal gland and makes it almost impossible to astral project. heres a link:
P.S. Listening to music is like a free EEG, when the music goes faster, your brainwaves are going slower.
