One night while my mom and I were visiting my aunt who lives in my great grandparents house on the second floor. We were all already in bed, lights off, regular night it was probably 11:30pm. My aunt gets out of bed and says she’s thirsty and wants to go get something to drink from the kitchen. My mom was in her own room across the hall and the kitchen shared a wall with where I was staying with my aunt. Keep in mind it’s an old house and you can hear everything, all the rooms are close together. Any way, she leaves the room and I hear her go into my mom’s room. I’m still laying in bed, lights are on, just waiting for my aunt to come back. There was a window across the room from me with a shear curtain closed over it. I started hearing someone or something from that window calling out to me getting louder and louder. It sounded like a “pssst” and then again “pssssst”. I started freaking out and yelling out to my mom and my aunt as loud as I could. They couldn’t hear me. The “pssssst” got louder, and my entire body got chills. I began crying because my mom couldn’t hear me screaming out for them. I was terrified. I just knew and felt something on the other side of that window was staring at me. Remember, we are on second story building, like upstairs, not at ground level. No one could be walking by outside etc.. Any way, I got so freaked that in such a small old house no one could hear my screams, my fight or flight kicked in and I BOLTED out of that room over to my mom’s room. My aunt and mom both looked at me dumbfounded because they thought I got hurt or something. My face red and wet with tears and panic. I told them I was yelling out for them and they said they couldn’t hear anything at all. When I told them what happened they stared at each other and in order to calm me down they brushed it off saying it was some sort of animal or bug that makes that noise. They’ve had their own terrifying experiences in that house so I know they were just saying the bug story to not let me freak out more. That event haunts me to this day. I was 16 years old when it happened, I’m in my 30s now and I can still remember it vividly. I don’t know what dimension or void or block that thing calling out to me engulfed me in because for no one to hear me still freaks me out to this day.
