NoAlice didn't see Bella getting hit by the car (that is what you meant wasn't it?) Edward just happened to be in the right place at the right time. if you read the fist 12 chapters of midnight sun then you find out that the Cullen family were furious with Edward for publicly showing his speed and strength.
In the "Twilight" series, Alice Cullen has the gift of foresight and can see possible futures. In the scenario you are describing, Alice has a vision that Bella is going to get hit by a car, so they send someone to intervene and prevent it from happening, just in case it does occur in reality.
In Twilight when Alice has a vision she completely blanks out so, someone has to make sure she doesn't do anything that she will regret after wards.
Yes
before twilight came out people said "a vision of twilight might be..." it means what do you think twilight will be about
It could strain your eyes, I guess, but that could happen to anyone really. Apart from that, I can't think of anything major that could happen.
A vision is a day dream or thought of either something a person feels is about to happen or of something that did happen (the latter is called a flashback).
not really black=thristy gold=full
no they comfort her so she tells them what she's seeing at the time
Jasper always stays with her, but otherwise Alice doesn't need anyone to take care of her when she's having a vision.
Really! Why does this happen? (Btw actual question)
No, not really. It's kinda like a vision of one possible future. Although it not likely to happen. It is an ongoing vision of the future.
they all die but its not really a real fight , its just alice's vision (of the fight )
nope :)
