Personally, I know of the Jackie Hernandez case, in which a paranormal investigator was allegedly attacked by an invisible force on two separate
occasions, one of which was photographed:
“The Entity” case, in which a woman named Doris Bither claimed to have been repeatedly attacked and even raped by a ghost:
And the Smurl case, in which a family’s daughter was attacked and the father sexually assaulted:
Does anybody know of any more? Or maybe you have a personal story you could share with us?
