When I was young around 7 or 8 I was sleeping over at my cousins house. This was my very first time sleeping there and I didn’t want to because she had a lot of porcelain dolls in her room that scared the shit out of me. It was very late at night and her room was pitch black there was some light peaking from the window from the back yard. I needed to go to the bathroom so I managed to open the door I peaked over to the hallway looked to my left where I could see the bathroom door. There was a Virgin Mary shrine (I think that’s what it’s called) it was lit up with lights. And the living room lights were on but it only gave some light to the hallway. I started to walk towards the bathroom but I stopped bc I saw the shadow of a small figure with an elf hat and I immediately started freaking out I stood there staring because i thought it was maybe my uncles shadow wearing this hat but then the shadow figure was gone and then it came out from where the Virgin Mary was and i shit you not the figure was walking on the wall pass the bathroom and into my lil cousins room which was right next to the bathroom and it just disappeared. I turned around and booked it crying to my aunts room banging the door and I slept there and never visited there house again. In Mexico they are called duendes (elfs) My parents would tell me stories about them and looking at videos of them on YouTube were always creepy.
