Yes, I have this problem too. I was trying to WILD, napstyle. Took about twenty minutes to get to the vibrations. I felt like the skin around my lips was getting hot, and my hands were stuck in place. I didn't really hear a ringing, but it was probably because I was so excited. I couldn't really control my eyes, and they were moving all over and trying to open themselves. I couldn't concentrate, and that was my first WILD attempt. I am pretty psyched because I just found out about all this stuff yesterday, and have yet to LD. I'm going to try a WBTB tonight, though.
