When I was a kid, there was an underpass to cross the station at the foot of my residence building. It was a pretty creepy place and a good one for shady stories (women raped, agressions, robberies and so on...)
Every wednesday, I was taking swimming lessons. The pool was on the other side of the train station, so I had to cross that damn underpass, but I was a bit apprehensive about it, considering what I said above.
Nothing notable has ever happened to me in this underground passage, but I have met some very shady guys there... One day as I was on my way to the swimming pool, arriving at the end of this creepy underground hallway all tiled in white dirtied by the time and badly lit with yellow lights I heard screams from the street above. It was the cry of a begging man.
Suddenly a tall, thin man with a hard look in his eyes and a sunken face entered the underpass. He was dressed in a long black robe and looked like a priest, walking at a brisk and determined pace.
In the distance still those screams, getting closer as the priest came to my height.
The vision of this man followed by cries whose reason I could not identify was already enough to make me feel a certain fear mixed with a feeling of unease.
As the tall man in black passed me, I discovered where these cries were coming from: a small, hunchbacked man stumbled down the stairs, his face twisted in a grimace of panic and ugliness, hobbling behind the priest and begging him "wait for me father" in desperate cries.
When I think about it now, as a grown man this story make me smile even if I still don't understand what was going on (at some point I believe it was some prank *) but as a kid it was a really weird epxerience.
