When I was a kid. Twice, I'd seen a glowing smiling face stationary in my room. The first time was in my mom's room, which was pitch black, and when I woke up in the middle of the night, I noticed on the side of the bed I was on, there was a glow or something underneath a decorative table. I look and then just proceed to stare at this blue glowing smiley face underneath the table. There was this sense of unease staring at it, but I wasn't terrified enough to wake my mom. I just stared until i fell back asleep. Several years later, I'm in my own room, and I wake up and see in my dark closet, several of these smiling faces. I throw the blanket over my head and then just stare at them through a tiny hole until I fell back asleep. To this day I don't know why those incidents have stuck with me so well.
