The one year anniversary of that apparition of a dead person would be May 13, 1918. However, if one transposes the 18 as the writer of 1984 transposed 1948, you will have the date May 13, 1981.
Did a significant event in the history of the world happen to a pope on May 13, 1981? Who would have been the Pope then? Where was he on May 13, 1982 (answer - Fatima, Portugal)?
Anyone can do a google search on Fatima, Portugal, Miracle of the Sun, the dates 13 May 1917 and 13 October 1917 (which both predated "Red October") and was predicted by the children (Russia would spread its errors around the world).
Oh good grief!
I see you are a superstitious type of person that wants to believe this nonsense.
Truly, DEAD people don't talk or appear. Only ONE has risen from the dead and that is Christ. All you're calling attention to is the work of Satan and other fallen angels. Fatima is another "wonder" of Satan.
