Story 1:

At 4 a.m., I heard a singing voice on my baby monitor. It kept saying, “Hush now, baby, I came for you.” We were alone. When I got to my baby’s room, she was sleeping. I tried to reassure myself that it was only a terrible dream.
But when I was adjusting her blanket, I spotted something beneath her arm. My blood raced cold when I discovered a message that said, “Make sure to take care of your child more!” I felt ill to my stomach and froze while holding the message.
Hours later, I fell asleep in that position. When I woke up, the note was gone. I searched everywhere; it had vanished. I still wonder if it was all a bad dream, but I know for certain it was not—everything felt so real.

Story 2:

When I was approximately 17, my buddies decided to conduct a ghost hunt in one of their homes. The girl who lived there and her sisters were frequently talking about strange ghostly things that happened. I was a skeptic with nothing better to do.
Around 4-5 hours later, I was seated on a chair next to a locked door. The doorknob twisted, and the door opened halfway, then completely, before slamming shut. I suddenly felt footsteps near the chair. I am no longer completely skeptical. copyright Jado9814/Reddit

Story 3:

When I was fourteen years old, I spent the summer with my grandparents. It was eleven p.m., and I was thirsty. I walk out to the kitchen and see who I believed was my grandfather seated at the table eating a sandwich. I say hi, take a drink of water, and return to my room.
My grandfather emerges from his room and inquires as to who I was speaking with. I turned back, but no one was there. It terrified me and still does to this day. © Lucanthethird/Reddit
