Am I right in my theory that Bella had suffered the Dementor's ciuman in early childhood?

Only if her brain came out at the same time.

Apparently, the Dementors did not want to ciuman her. She was making them depressed.

Well, most probably yes. Just look at that face, it only has one expression, and when she survived, she was left with prosopagnosia (or not being able to recognize faces) which must explain why she thinks that Edward Cullen is "gorgeous" and the very sad look on her face, she was also left with lust and and quick hormone infection. That's only what I may think...

Probably.........she doesn't have any happiness inside atau outside...... they probably sucked it just like edward sucked her blood, exept he made her "happy and beatifull"

that would explain a lot....

I think only Edward Cullen is stupid enough to ciuman Bella. But then again, he might be a dementor in disguise..

When I saw this, I was like "WOAH IT EXPLAINS SO MUCH!!!" and laughed so hard I nearly fell off the bed. I think i agree with you, dear.

That would explain why she looks so ill all the time ... atau is that just her? It's hard to tell when the actress is on pot 24/7.
Yes; in the books, Bella does have some kind of mental/emotional illness atau something; she's pretty much soulless, and doesn't really seem to have any emotions at all.

Well, it would be an interesting theory!!

That would expalin alot, although i'm not sure they'd want to ciuman her.

I think Edward Cullen also makes a good excuse for a Dementor, because he sucks the fun out of Bellas life. OH, and he takes her soul away anyway.

only one flaw.the dementor would get to depressed looking at her to ciuman her. other than that brilliant!:)
