Okay. I'm back with another question on DEILDing.

I've been using a WBTB + DEILD combo almost every night for the past month or so.
After my WBTB (still haven't found a good time, but I'm getting there), I lay down to sleep and start saying a mantra, something like, "I remember to not move or open my eyes when I wake up." And then I try to say it until I fall asleep (although I usually can't keep it going that long), and then before I know it, my alarm goes off to signal the start of a new day.

I don't know if I'm doing anything wrong. How will I know if I will wake up? I know that we wake up after dreams but we aren't always aware for it. It just seems like I'm getting no where. Any tips? I feel kinda lost. Sometimes, after saying the mantra, a couple hours later I will wake up and move as if I never said it at all. Before I know it I've already moved.

Basic questions: How do I become aware when I awake? How do I know if I will wake up after WBTB? Should I use WBTB + DEILDing?
