Yes, there are a number of ghosts who apparently haunt Auschwitz...
1. Irma Grese, "the most notorious SS guard in the history of Auschwitz." She was hanged. After a number of people refused to be the hangman, Samuel Lutzheim, who was Jewish, was chosen. She "swore that she would return from the dead if Lutzheim was allowed to touch her." She was hanged in 1945 by Lutzheim. The first sighting of her was by the night watchman in 1948 in the crematorium. Leni Riefenstahl, a German film director and actress, wanted to make a movie about the haunting, but the government said she would be arrested if she tried.
2. "Birds still refuse to sing in the trees surrounding the death camps and there is little evidence of a thriving natural environment anywhere nearby....
People have reported cold spots and areas of intense emotional concentration. Recent reports have come in that while touring the camp some have been touched or even grabbed by unseen hands. One visitor report that someone or something tugged on her clothes and she heard a voice whispering to her but could not make out anything but one or two words. " Please and leave"!...
Photographs over the years have revealed the presence of spirit manifestations in the form of misty apparitions, shadows, light anomalies and orbs.
3. Paranormal investigator Troy Hodges went there: "After he got stationed in Germany, Hodges and some friends brought an infrared camera and other equipment to Auschwitz. Again, he said the equipment somehow picked up many orbs, which aren’t visible to the human eye."
