Oh! and this other dream I had might be relevant too~!
I think maybe it was two years ago, I had a dream wear I could only look up ...while I was being chased by t-rex in a Alice n Wonderland type setting lol
Who knows wear that came from . - .
But, you know the reason I could only look up? I was hunting and fell asleep with my head laid back over a tree branch, in the same problematic position as the dream.
SO based on those dreams of mine I'd definally say your physical shape has some sort of play in your dreams. But I ain't no expert or nothun =.=
