So glad I have a story to share the same day I created my Reddit account!
About four years ago I was sleeping and woke up randomly to see a person standing next to my bed. This person was clearly female, but very petite -- perhaps a teenager or just tiny in stature. She was facing away from me and had her shoulder cocked up to her cheek, like the way you sometimes see people holding phones. Her hair was in a low ponytail.
There was nothing surreal or ghostly about her. She appeared exactly as you would imagine a person would if you were to waken in a dark room, somewhat illuminated by moonlight. There was no mistaking the fact that someone else was standing only a couple feet away from my bed.
I jolted upright immediately. Shock is putting it mildly. I remember my heart was POUNDING, POUNDING, POUNDING. The worst part about it was... she heard me sit up, and reacted, turning her crooked head around to face me, as if equally surprised to see me as I was her. I was so scared I actually closed my eyes, like they do in the movies, thinking that when I opened then she would be gone and I could chalk it up to some kind of half-dreaming state.
She was still there, staring at me. I started to fumble for the lamp on my nightstand. It felt like god damn forever -- I couldn't take my eyes off her. I was so nervous that the noise would further prompt her to come towards me, or something. When I finally switched it on, she was gone.
I called my boyfriend, hysterically crying and begging him to come over. He refused, and said I hadn't actually seen what I thought I had seen. I slept with the light on for three entire weeks, I was so scared. I remember I told my mom the next day and she advised me to search every closet in my apartment for squatters, which is perhaps even more terrifying than a ghost appearance, thanks mom!
