I made a recording a couple days ago of my own voice, saying "You may be in a dream. Try a reality check now."
It played after every 5 minutes of silence the first night, but I couldn't get to sleep because I'd always end up focusing on the audio, waiting for my voice to come on again. Or my RC would ruin whatever relaxation I went into.
Last night, I had it play every 20 minutes, after the relaxing "Subliminal Dream recall" mp3, with little success, but I SWEAR I did a reality check by plugging my nose and I could still breathe through it. I didn't wake up or anything, I just don't remember anything after that.
I'd like to know if anyone here has tried something similar, to any success?
