But there are two echidnas remember? One was in the tomb and the other one was controlling the dream castle, they didn't looked anything similar You do realize that those were the exact same?

This is Echidna in the tomb, the body.



This is the Echidna in the "dream castle".

They are the same Echidna, only the above one is her actual body, with this one being her soul. If you're talking about Echidna (Artificial Spirit), I highly doubt she has any relevants in this theory.
