I'm not a teacher but for me a MILD is when you wake up in a dream either immediatly knowing or suspecting your dreaming. All other DILDs for me is when you become aware you're dreaming after more of the dream has gone on for a bit. So, a MILD is more like a super DILD! That's how I see it anyway.

Also, I noticed one of your short term goals is to fly faster and more stably. I discovered in a recent LD that if I spin while I was flying in the air I could stably fly a lot faster. This worked for me both when my body was vertical and when it was horizontal. It might be something to try out!
