Not WW2 related but have seen a Ghost of a Preist/Monk in the old medieval cottage we used to spend our summer holidays in Harlech, N Wales. It wasn't a shadow and it was stood thru my bed! Funny how monks crop up in ghost stories; one once cropped up in a dream i had while camping alone. In the dream i was out of my tent in the night, following a monk-like figure across the field towards a clump of trees that seem to have an 'aircraft' in it in a clearing, and there the dream ended. Next morning i woke up back in the tent normally, and noticed a bruise on my shin which wasn't a bit painful to the touch and i had no idea how i'd got it. People who are into UFO research tell me that i might have been abducted by aliens who took DNA/bone marrow from my shin, and that the 'bruise' was an anaesthetic/painkiller.
