Wait, I thought the purpose of life flashing before your eyes is that the brain is trying to find a past event, that might help avoid the impending death. On QI, though I cannot remember the episode, they told a story of a swimmer, who encountered a shark, and suddenly his life flashed before his eyes, thinking he was going to die. In the slides of memories, he saw his son watching a DVD about punching a shark on the nose. So he did, and it saved his life.
That explanation makes a lot of sense to me. The brain is convinced that death is imminent, and has no time to go through the normal procedure of remembering, so it just pulls up as many memories it can to the forefront, in hope that one of them might provide the answer to prevent death.
