Instruction Manual

Why are there no instruction manuals or self-help books to tell you what to do when you die?

Are you meant to just hang around in spectral form for something to happen? Are you meant to have a little holiday? Maybe you should haunt someone who has annoyed you? Stand for a while in a very British queue? 

The religious texts of the various religions are peculiarly devoid of instructions on what you should do, despite the many reports of people coming back from the dead. They're full of instructions on what to do while alive and in an effort to reach the afterlife, but bugger all on what to do when you get there, which seems like an anticlimax.
