Archive X Paranormal Stories, which is a section of The Virtual Library, contains a collection of more than 3500 stories about paranormal phenomena. The categories listed in the main index are ghosts, angels, channeling, near-death experiences, out-of-body experiences, stigmata, and past-life experiences. But a perusal of the site reveals that other subjects are also covered, including shadow people, ouija boards, spirit guides, possession, and astral travel, to name just a few.
The introduction to the section on "True Angel Stories" says that angels are divine messingers sent by God to impart important information. But it also says that in many of the stories angels act to rescue people from dangerous situations such as auto accidents or possible drownings. In addition, it mentions that angels can disguise themselves as everyday people, so that someone could be helped by an angel without being aware of it.
I read a story about a woman who was walking down the street to visit a neighbor when she was suddenly warned by a mysterious voice in her head not to go any further, and so she returned to her own house. Later that day she found out that the neighbor was shot and killed by an intruder just a few minutes after she heard the mysterious voice.
