I have got this method which probably alot of other people use but for me it works almost every time but i don't know why. It's a form of (MILD), i just wake after about 4 to 5 hours, get up and go for a walk around my house to wake my mind up then go to bed and repeat whatever phrase i choose. Last night i chose "i will realise i am dreaming" and i did just that. I remember becoming lucid spontaneously but my dream self felt like it had been run over by a car and if i tryed to walk it was like slow motion, so i decided to wake up. That was the first time i have used that method for quite a while and it worked for me again.

Have you got a technique?
