I Have Some Questions

Some might not be exactly questions, but I need some input on them.

1. Did a WBTB, and got lucid for the second time, but as soon as I did everything slowly faded to black. I think I woke up, but I am not sure since I heard that sometimes you just dream you wake up when this happens. I am not sure because of the fact that I woke up, thought to myself "at least I became lucid" and then went back to sleep, although I barely opened my eyes and never surveyed my surroundings or anything.

2. Before I went to sleep during my WBTB, I tried to WILD, and actually got HI for the first time, it was just some blobs or orange color. Although every time something happens (Vibrations, Spinning, anything) my breathing starts getting fast and I lose my progress because I have to take a deep breath to calm down. Suggestions? This also happened to me when I woke up on the same night and tried to DEILD.

3. When I got HI, how close was I to dreaming?
