Harry Houdini is kidnapped in Egypt, tied up, taken to an unknown location, and dropped down a deep pit, where he witnesses an army of half-man, half-animal mummies leaving offerings to a five-headed, tentacled beast.
A man discovers, at the age of 30, that his daily waking exposure to the more practical, scientific ideas of man, has eventually eroded his ability to dream as he once did, and has made him regretfully subscribe more and more to the mundane beliefs of everyday, waking real life.
The End of the End of Everything, by Dale Bailey, is an sf/horror story about a long-married couple invited by an old friend to an exclusive artist's colony.
