Hi Galen, I am not surprised by what you tell us. I have relatives working in a building in Madrid, in which during the Franco regime, not so long ago, terrible things happened. The workers who work in the basements talk about the apparitions of a being, it seems that of a detainee who died there, and they also say that the lights turn on and off, that they notice that cold you are talking about...
Although looking at the photo, no one would say that it was such an oppressive place.
Greetings Galen
It's interesting how some places have occurrences and others do not and I wonder why sometimes. I've been to a lot of very old and historical places and not all of them have the feel I mention. I guess it depends what happened there.
It is a mystery, but it seems that in some places the suffering is impregnated.
