I know what WILD and DILD is but what is WBTB and MILD?

I have only ever had DILD maybe you could say I had a WILD when I dreamt withouth ever falling asleep which is the craziest feeling ever it feels like you are in two places at once because you can control two different bodies that are in two different places. But if you do more than maybe turning over in your bed in real life you might lose the dream.
