I tried the reverse blinking for the first time last night. I hadn't slept previously - was just going to bed normally so I didn't have high hopes.

However... after probably only 5 minutes of the reverse blinking I heard a loud sound - almost like a symbol crashing behind my head. I think this may have been the beginning of sleep paralysis (I was feeling more relaxed and detached from my body than I ever have before). This was quite exciting since I've never experienced SP (or for that matter, WILD) before. I got too excited and woke up before anything else happened, but I'm definitely going to be trying this again.

Thank you Sythix!
