hei there ! I have a soalan about New Moon: Why does Bella see all those "visions" of Edward warning her whenever she is in danger? Edward can´t read Bella´s thoughts. Is Alice the one that see that Bella is in danger and warns Edward?

actually Edward is not there nobody says nothing to him. Bella just can see him because he's in her subconsiente. U know in her mind!

I'm not sure what you're talking about. Are anda asking lebih than one question?
Anyway, Bella sees the "visions" because she's holusinating, lol.
Saying that she misses Edward would be an understatment, but that's basicly why. It explains later in the New Moon book that the real reason why was because the bond between them was so strong, and part of Bella still knew that Edward loved her lebih than anything.
It's not REALLY Edward getting into her head. Edward doesn't even know this was happening until after they get back from Volterra.

Alice can only see when bella jumps off the cliff she cant see if she was saved atau not because Jacob saved her and she cant see Jacob. alice leaves to go see if Bella died and finds out she didnt. Then when alice and jacob and bella are talking in the dapur edward calls and jacob awnsers edward says " where is charlie?" hacob says "planninfg the funeral" so edward thinks its Bellas funeral.

Bella sees Edward because she "misses" him. After the few months pass, her father tells her that she is like an empty shell. There was no "life" in her. He tells her to be social again, otherwise he'll send her to be with her mom.

When her and Jessica hang out, she sees men in a bar (from the book, not the movie). She goes toward them. This is as close to danger that she had gotten since Edward left. Since she had spent months pining and desperately needing him, she hallucinates and "hears" him atau "sees" him.

This became her addiction. The hope of seeing Edward. She'd do anything to see him again, even if it meant putting her life in danger. It was proof to her that he and his family were real.
