Sleep paralysis isn't scary if you don't expect it to be scary. But to answer your question. No! You wont get a mind awake body asleep experience in WBTB.
About the dream, you are on the right track. When I started LD'ing, there could be written Lucid on the walls and I just walked past it. I'm stil getting some of those dreams, and it's nothing bad about them
When you said that you do RC's very often, remember that it's not the quantity that counts, but the quallity. Don't cut the RC rate down, but remember to really question reallity.
Good luck in your dreams
