In the first dream, Monica looked like Vanessa, the Sea Witch's alter ego from The Littler Mermaid. (Pic Related) But her hair was a little more brunette and she had Princess Leia buns in her hair.

In all subsequent appearances, she's had raven hair and has more closely resembled a young Monica Bellucci.

I guess my brain registered that I was attracted to "Monica" and adhered itself to the most attractive person to have that name. (Not that I'm complaining.)
