You did not read my post.
I said the elements of a human.
Dreams dont fit in.
Aunbirth can not be born of something that does not have a physical form.
Which i can usually explain to you.
Actually, something CAN be made out of nothing. The Keyblades themselves are more than enough basis for this.
Specifically, the Keyblade or at least the Keychain Riku used on the Keyblade he gave to Kairi was made of his Memories of Destiny Islands, thus your claim is nulled.
That aside, I stated often, as well as in the topic post, that Dreams are possibly based on the Soul.
The one that doesn't read posts here is you.
