Here's my personal experience if it is helpful:
I've had both astral attacks during sleep that result in my prematurely "waking up" from the dream hence I'm not completely in my body. At times I am above my body so I see a few feet above & have that point of view. Not pleasant. In everyday life I can only "see" beings if I am focusing on that part of my sight..something I don't try to do nowadays as it tends to freak me out.
I also had a visit from what I think was an angel one time & it was standing on my windowsill & this was the closest thing to a lucid dream I've ever had because it was crystal clear, I was conscious & aware it wasn't my real life & anyways.. I digress. I could see my room but it was warped because the window was much bigger & my closet had shrunk (right behind the window). So... well, if all the mystics are right & this reality isn't as real as we think it is.. maybe it can be warped if there is a purpose so maybe what we see when we're paralyzed is just a different view of what exists?
However most of the time when I am sleep paralyzed I see what is exactly as it is around me. Sometimes I will see shapes of my blanket or stuffed animals..whatnot that are around me.
