Hey guys, i’m a newb to all this LD stuff 
I was listening to the Hemi-Sync tapes, and I was on the advanced one I believe…and when he said when he counted to 20 i’d enter natural bleh bleh sleep, so right when it hit 20, I felt like I fell through my bed, I could see white like, through my eyes, I heard humming, perhaps the tape’s fault? 
and then my heart beat extremely hard, but then my cell phone rang…do you think I was close?
to the forum, btw!
