It happened in the city of Monterrey in the late 1980s. My family (the side of my mom) is very large. My grandparents had six daughters and one son. The second oldest daughter, we'll call her Lisa, has always had something with the paranormal. It's like it follows her.
Before she married, when she was around 21 years old, she and her sisters had to share a small room. She shared a bed with my other aunt, Val. Aunt Lisa told us that one night that she and Val stayed awake after midnight talking, which was usual. She had her head turned toward the window that fronted the street, while Aunt Val had her back to it.
Aunt Lisa looked to the window suddenly and saw a "thing" standing on the branches of a tree that was just outside the window. She said it was staring at them. She described it as an old woman who was short and pot bellied and dressed in all black, but her clothing (or whatever it was) actually looked like black feathers. And her eyes were blood-red. No pupils, no white, just all red and shining.
At first she thought, "It's just a bird," but it had the unmistakable face of an old woman. She never tore her eyes from it because she didn't want to be called "crazy" or "liar" and she thought that if she looked away, the thing would disappear. So, although she was dead-scared, she kept staring at it.
She told Aunt Val, "Look out the window. What is that? It has red eyes." And Aunt Val got scared. She closed her eyes shut and said, "No, I don't want to see anything." Aunt Lisa started shaking her, begging her to look at it, but Aunt Val didn't. Eventually, Aunt Lisa became so scared and impatient that she ran to the switch and flicked it on. And then the light bulb exploded. My mom told me she screamed the most horrible, blood-curdling scream, waking everyone up.
When she started telling everyone about what she had seen hardly anyone believed her, even though she was frantic and weeping uncontrollably. But there was nothing on the tree, there was no one outside, no one else had seen it. Eventually, everyone seemed to forget about it.
This is the weird part. By around 2005 and 2006, there was this story on the news about two cops who had seen something weird they called a "witch". You can actually see the interview if you Google "Bruja en Monterrey" (which means Monterrey Witch) or something, but the interview is in Spanish, so I'll translate what one of them said: "I saw a woman dressed in black with feathers, and two black claws." The other cop said it was flying.
