gosh sorry for the late reply lol, but FILD is "Finger Induced Lucid Dream" and is a very successful method to WILD for many. DEILD is "Dream Exit Induced Lucid Dream". It normally is taken advantage of when waking up from a lucid dream or a normal dream, where you gather your awareness, don't wake yourself up too much, and re-enter the dream usually in a matter of seconds. At least that's how it was for me. It's basically like WILD without all the difficult preparation part because your body is on the verge of sleep anyway.
