Well definitionaly, there is no atheist view about the afterlife. Not believing in a god does not preclude believing in an afterlife. But, practically speaking, I don't think you'll find many atheists who believe in an afterlife, or ghosts, esp, or unicorns, for that matter.
If there is a god, I want to believe that there is a god. If there is not a god, I want to believe that there is no god.
