This took place in Tijuana, Mexico. When I was a baby, my mom and dad shared a house with my aunt because it was located in a kind of dangerous neighborhood for young people to live by themselves. They sticked with this house, however, because it was not an ugly house at all. Its decoration was very nice, my mom said it looked like the previous owners put a lot of effort and money to make it a great place to live. My mom felt a strange vibe, though, but she did not say anything because they often had family and friends visit and she didn't want to scare them off.
After settling in the house and having everything in its place, my mom finally had the time to check every detail of the decoration. She soon realized that what looked like trees and flowers on the walls were really silhouettes of people making out or involved in other sexual activities. She didn't tell my dad or aunt because probably they were going to make fun of it, but then it slipped out in a conversation and they told her she was not wrong.
After a few weeks, my other aunts started asking my mom if she could visit them instead of having them come because they felt something was going on in the house. My mom agreed, she knew they were right. One day while cleaning the house, my dad hit the wall and it felt like there was an empty space behind. He started ripping off the wallpaper and they found a small door. They opened it the next morning because it was almost night time and my mom was afraid of what could be inside it.
The next morning they opened the door and there was a small closet, they did not find a dead body, a hidden treasure or something that made him rich, no. They found night gowns, old make-up, slippers, fantasy jewelry and other stuff. That's when it hit them, the house we were occupying was an "entertainment house" in the past. And even though this did not disturb them, they decided to move out after an evening when something scary happened. My mom got home and put me in my crib, she was tucking me in when she heard my aunt say "Diana, llegaste?" (meaning "Diana, you're home?) My mom replied and when she went to my aunt's room there was nobody there, she picked me up and waited for my aunt or dad to get home in the living room with the door opened and turned every light in the house on.
After moving out, they were curious and did a little research. They found out that the house was previously owned by an old lady who ran a prostitution business. She hired someone to install a new set of curtains and when they were ready, the employees stabbed the lady and stashed her body in the basement. The rumor was that she had a chest full of money and her killers went after it. Her body was found by a prostitute who was the first one for 'work', according to the information given to my folks. The girl found the house completely trashed and not being able to find the lady in any of the rooms she went to the basement, that's when she made the gruesome discovery.
All this information was given to my parents by a neighbor, the old man told them he was close friends with the murdered lady (I personally think they also sustained a business relationship).
