Has anyone really paid attention to what dreams reallg look like from a raw, visual only perspective?

When looking closely at why I have multiple fingers, it appears sometimes as multiple instances of my hand superimposed and clipping into one another. Sometimes things grow and shrink like a kaleidoscope lens, and other times it's full HD with pixelated edges, with just two or 3 instances.

I want to make a movie or a scene in a movie that looks like dreams, and so far I'm mostly getting "Blurry but somehow HD."

What other details have you noticed?
