trying to find a (weird fiction / science fiction / horror) short story collection I read as a child - seem to remember it being hardcover, quite large and square-ish - some of the stories I remember:
- An opal gatherer or miner has a meeting with aliens, and what comes back doesn't have any pupils (or possibly irises)?
- A man learns to astral project but goes away so long people think he's dead and they bury him and he comes back trapped in his rotting corpse
- Something about doppelgangers?
Any help greatly appreciated :)
