None during my service or travels, but just before I got married I bought a Black lab pup, it had the run of the house and used to come up to my bed and lie between the wife (now ex) and myself.
She had it out for a walk when it was about 9 months old, it got off the lead, was knocked down and killed.
About 2 weeks later we were in bed sleeping and both woke up because we felt something jump onto the bed and lie between us, I was'nt frightened, but I felt comforted that the pup came home, so to speak.
Yes a very spooky drive past there on the range road, never seen any birds flying over Belson. I spent a lot of time in Osnatrabruk in most of the barracks and there were lots of Stories about ghosts of German soldiers who were buried alive in the buildings cellars in Belfast and Roberts Bks.
IIRC, there was a block in Dortmund (can't remember which barracks, but it was one just next to the B1) that had a huge swastika on the wall from pre WW2 - and no matter how many times it was painted over, the damn thing would fade back through within a couple of weeks.
