Vibrations

[Magickist]

Hello, a few nights ago I attempted astral projection by using an entrainment CD that used binaural beats\voice, particularly used to induce the vibration state. When I had gotten to the point of the wave frequencies associated with the CD and the guy in the background helping out, I almost immediately felt a difference in my body. My body had become warmer than before, and it felt a little tingly and slightly heavier than before, and I can almost say that I did feel slight vibrations pushing through my body, below the chest mostly. The problem with this however is, disregarding all that occurred I could still move/feel my physical body, but I did hear a buzzing noise in my left ear for quite some time, sounding almost exactly identical to a bee. Can someone please explain to me what happened and what I'm doing wrong? I would also appreciate it if you can tell me how to correct it and how to get on the right track. Thanks.
