I saw a reference in the M.R. James podcast (A Podcast to the Curious) to "Twelve Medieval Ghost Stories" by M. R. James: https://www.mrjamespodcast.com/2015/12/episode-49-twelve-medieval-ghost-stories/
I found that they were printed in a historical journal .. but were in Latin. I wonder if they would attact one of our Latin readers?
They were mentioned in The English Historical Review vol 37 number 147 July 1922 ( https://www.anselm-classics.com/byland/about.html )
Here's the journal page where the article starts: https://archive.org/details/sim_english-historical-review_1922-07_37_147/page/412/mode/2up
