It seems like DEILD, but I'm not sure.

I set an alarm to wake me up when I'll be deep in a dream (about 30 minutes to an hour before I normally wake up) and immediately turn off the alarm and lay back down to sleep again. I don't do anything to try to wake up further, all I do is repeat to myself like a mantra 'i am dreaming' so I don't forget, so as soon as I am dreaming no matter how illogically I was thinking I couldn't possibly have forgotten that I was dreaming because I just said it. Usually I only need to say 'i am dreaming' 5 or 6 times before I'm asleep.

I don't try to visualize or anything, I just repeat the mantra and trust that I'll fall asleep very quickly.

So far this has worked very well when I time the alarm right and the faster I lay back down the better.
