When I (believe) I had an OBE (the beginning of one at least) I was laying on my bed and after a while I noticed I was looking at my TV stand and junk in my room. I just stared at the same spot until I realized I couldn't blink. Then it dawned me that my eyes wern't open and I quickly forced them open and saw my TV stand again. I closed them not knowing what to expect but it was just blackness like normal. This had happend before I found that site and it pretty much described what happend to me. It's a fun thing to pratice though, that and lucid dreams...
