[Doctor Strange in the Multiverse of Madness] (SPOILERS) Question about Wanda

In what the film refers to as the 616 universe (not the one we know of as 616 but I digress), Wanda had two kids with Vision, but both the kids and Vision were fake, they were just things she created with her magic. However, she's able to find a universe (Earth 838) where the kids are real, and they're basically the exact same kids that she fabricated with magic.

Who the hell is their father? Is it Vision and he's just a real boy in this universe?

We don't know. That said, since she created her children with her mind, there is an easy explanation as to why our Wand's children looked the same: she dreamed of them.

We know that dreams are a gateway into other universes, so she would have seen what her children should have been. So, when she was instinctually creating her "perfect world", she shaped her children in the image of her dreams/other universes.
