Starting to visualize better

I'm starting to be able to visualize things better ... last night when I was falling asleep I could see a lot of things, and then just now, as I was falling asleep, I could see some kind of architectural drawing, and I was looking at it, and then I became a little too conscious, and it went away, but I just wanted to note that my ability, first my ability to visualize things is getting a little bit better, and that it seems important just not to use, just try to use the real physical eyes ... and then second I just wanted to note that I was starting to have this dream before, long before, I really felt like I was physically ready to fall asleep.
