my great aunt who lived in Mexico growing up, she said that when she was a kid, her and her siblings would hear unexplained noises coming from their basement or sometimes see a small light coming from under the stairs leading down there . This happened a lot but they were kids and too afraid to go look. this was a long time ago, probably back in 30s or 40s…back when people didn’t trust banks like they do today. basically long story short after my aunt and her family moved out of their house, and they were knocking it down to build a new house and they found a box filled with money and jewelry buried under the floor of the basement. Till this day my family believes it was the previous owners spirits trying to tell them about it.
