Last year, Ken R. Vincent reviewed 1667 cases on the After-Death Communication Research Foundation website. A total of 336 (20.1%) were found to be one of three types of evidential communications:
(1) apparitions appearing prior to the experiencer’s knowledge of the death of a loved one. These numbered 180 (10.8%) of the sample.
(2) apparitions appearing to multiple witnesses. These numbered 57 (3.4%) of the sample and
(3) apparitions that convey knowledge unknown to the experiencer that is later proven to be true. These numbered 99 (5.9%) of the sample. Read more.
