The White Light

In both novels the characters talk about right before they die they see a 'white light'. Many people believe that before you die you see this same white light appear. My mom was in a car crash when i was 13 and she is very lucky to still be alive. She was in very ruff shape. A car was speeding on highbury going out of London and my mom was going in, the car hit black ice swerved and t-boned my mom's car. The other driver wasn't wearing a seatbelt and died instantly. My mom said she saw a white light that morning.
Susie says in the novel that before she went to heaven there was a raging white light ahead of her and Sam as the car rolls and she is slowly dying she also explains how all the can see is a white light and she can feel anything.
Some people believe this is called the tunnel of white light. Many people have seen this light that associated with a near-death experience, and your go back to many old memories from your entire life and you see them all flash by you extrememly quick.
Maybe this is just a myth about the white light and maybe it is just in peoples heads that they will see a white light and possibly just think it. I believe in the 'white light', do you?
