that sounds pretty interestong ill have to try that hmm i wonder why[:D]
This morning I was playing around with different intervals for the surprised body thing. I was looking for a good position to lay in where I would stay there without ever moving a muscle to change the timer.
After about 25 minutes of doing one-minute intervals I started going from conceptualizing imagery directly into what seemed like 5 and 10 minute lucid dreams, even though the timer was set for one minute.
What would happen is, imagery would form in a static fashion. It wasn't really back-of-the-eyelid imagery, but more like it was straight from my brain. It looked grey like through a mist. It would turn itself on and begin animating, like I could watch plants blowing on a field.
Then it would drop into full color, and I would drift into the scene and have a lucid dream. I wasn't fully coherent even though it had a high degree of realism because I didn't really know who I was.
Anyway, it seems that using one minute intervals is a good way to explore hovering on that boundary without totally falling asleep. Of course my goal is to spend enough time on that boundary that I learn it and don't need the timer.
