this was my first dose i ever took. i didn't believe that i doser worked so my friends put this on for me and lets just say i KNOW it works now. the room was dark we used and iPod and an earphone splitter (doing it in pairs) i had a set of skull candies was blindfolded laying on a bunch of blankets for comfort. my friend said see you in a half hour then i was gone. as soon as the noise started it was calming and pretty relaxed. i started to drift into sleep. after what felt like an hour it picked up a little then all of the sudden BAM the loudest most unpleasantly high pitched noise i have ever herd. along with this cam a feeling of absolute dread and full body convulsions. i wanted to scream but couldn't make a noise then i felt cold as if i where freezing to death. i felt as if i was about to die when it changed noise again only slightly but i noticed i was in complete darkness. deep twisted voices and faint screaming was all i could hear then my body was forced to the floor and i felt like i was being crushed. my heart was pounding and i felt life being squeezed out of me and all of the sudden the darkness cam back along with the screams and intense coldness i was tense and shaking like crazy. and all of the sudden it stopped. the high pitched metallic noise faded back into the calm slow buzz in the beginning i ripped my blindfold off and was absolutely amazed. i was completely terrified and couldn't be left alone for the rest of the night. the kid i shared with couldn't make it and ripped his headphones off as soon as the high pitch started at about 22 mins in. all i can say is prepare to have all of your fears brought out and thrown in your face for the worst yet the best feeling.
