Hi Area 51!
Concerning tornados, I remember what Flo said about. She said they were very interesting and powerful dreams. She adviced to go into them. I remember too that she said it could put you into what she called the “intermediate state”.
A post about entering a tornado from an energetic point of view.
I spoke about the intermediate state here. It may interest you. It’s what you describe: an energetic void.
I had once a dream in which a strong wind pulled me toward the left. But I was afraid (I didn’t know as many things as I know today 
) and I woke up.
