Once a respectable English word, deriving from Old English /elles hwat/. Unfortunately it died out.
See also elsewhere, and compare elsewhen (1418), elsewho (1542), elsehow (modern).
It takes time and effort which might usefully be spent doing elsewhat. (The Face, NickLogan)
His mind was on elsewhat that hot summer evening after tea. (Memories of the Gorbals)

A version of the afterlife in the brillant novel written by Gabrielle Zevin by the same title. In Elsewhere you age backwards from the time you died until you become an infant again and are reborn. Elsewhere is much the same as life on Earth, you have to have a job so you have money to spend. You can watch people who are still alive though binoculars on the observation deck. The living can send you mail via bottles thrown into the sea. In fact, communication between the living and dead involves water...but I don't want to give too much away in case you haven't yet read the novel.
There are no supernatural beings in this version of the after life but there is Marilyn Monroe and Picasso; as well as some very colorful characters.
