After they died, the main characters created a shared realm within which to find each other. They initially forgot post-crash events and imagined new situations for themselves, but they gradually awoke to their previous lives. Mild deja vu, pain, unconsciousness and brushes with death sparked initial memories. Eventually, each character awoke fully after interacting with something specific, often a loved one.
