I don't have more knowledge than you, only own experience. It can look completely different for you, but when we dream we can dream anything.
We can start out in total darkness or we can see with our "eyes".
What's important is that the next time you make an attempt and get non-physical signs you should treat that as a dream, because what you are now is laying in a dream waiting to transition, but you are actually already there. There are tons of similar stories about people tryin to separate, experience weird things, but they just lay there and then they go to a forum asking what to do.
I was one of those people

Then I got my answer from the author himself on his forum (Michael Raduga):
Get out of bed!
