Paranormal activities in hospitals are plentiful.
Well there are a lot of deaths leasing to some unexplained phenomenon occurring.
My series of short stories involving spooky manifestations and cross overs from another dimension are based on accounts from friends and colleagues in the healthcare profession.
They cannot always be quantified by science but the fiction makes entertaining reading.
Visit my amazon author page and get a copy of either Phantasms in the Infirmary, Phantasms in the Infirmary Vol II, The Ultimate Phantasms in the Infirmary or Fantasmas en el Hospital (spanish version).
You can then make up your mind.... Are these Angels or demons.
Don't have nightmares!
