There are different types of wings that can manifest, in a sense. There are the basic bisymmetrical pair, a quad, a '6pack' as i call it, and sometimes 8 or 10. Usually the 8 or 10 denote a different type of spirit altogether.
Bisymmerty is typical amongst humans. Some have more. in the 4-coupling class, they come in a quadrant arraingement, or a layered arraingement (a 'la X-men). In the 6-pack/seraphim class, they can come in overlapping layers like a wing carapace, or in the hexagonal pattern typical of that class. From there, varieties come in shape. Some resemble that of a dove, and eagle...others, like mine so I have observed, resemble more of that of an albatross. The middle right one had a bend at the end, like a broken bone, and after some meditation and discussion, found it to be my astral "pimp hand." (IMG:

I have not witnessed an 8 or 10 form.
And THIS is just angelic-archetype wings. Others may resemble that of a bat, demon, gargoyle, dragon, phoenix, fish scales/fins, metallic partitions and sections....the possibilities are endless.
At least, this is what I have found.
No there are no physical manifests as of yet, so this is purely astral. although, at one point in time, my back muscles did bunch up alot at those points. For about a month those knots stayed in my back.
