Interesting projection... just to clarify, there are 5 separate "astral animals" that can represent a single animal percieved in the physical (according to your projection, of course)? If you hadn't added that bit of intuition I would've guessed you were looking at future evolutionary outcomes for every common ancestor, or animal that currently exists. The strange creature you describe sounds a lot like a pterosaur or prehistoric bird, suggesting a relation to the past as well as future. Perhaps the "astral animals" are blue prints of the past and future of each animal being percieved in the physical? Just throwing out ideas...
