I was about 8 days sober and falling asleep when all of a sudden I blacked out but I was still thinking like awake but asleep and no matter what I couldn't open my eyes, and then I felt this very strange tingle go up and down my arms, then I thought I was dying or something, I then forced myself like never before to open my eyes, and I did and the experience was over. Strange Shit, never found out what it was
