1) My sense of vision is terrible, and one night I was laying in the dark. There was enough light for the fan to have a shadow, and for some reason I saw the shadow as my grandfather in his usual rocking chair he sat in (he died years ago), so I stayed up all night until there was sunlight.
2) Every time I'm listening to something loud with my headphones, I start to hear some sort of nearby quietness that feels like a ghost or something near me. Once in a while I dramatically look around. Just in case.
3) I came home from school one day, and started to relax, when I heard my closet door trying to open. The door to my room is closed all the time when I'm gone, so I was extremely creeped out, and didn't touch it for a bit. Turns out it was my cat stuck in there, who was scared shitless just like me. The good thing is that I came home and opened my closet, left both doors open to go to the bathroom, then came back and simply closed my closet door.. so it's not like my cat was locked in there all day.
4) Quite possibly the worst of all, was one winter day, walking home by myself. It was the year I had just started walking home in 6th grade, and winter came; I was finally used to the normal route home. I saw this kid in a sweatshirt walking like he was kinda mad/depressed, walking quickly. He was on the other side of the street, walking faster than me, so for fun I crossed the street and walked past him. Eventually he literally walked the same way that I did, creeping me out, but I walked pretty fast, took a right, and looked back after passing about fifteen houses and didn't see him anywhere. There was no other way that he could be near me unless he was behind me. I walked past about twenty-five more houses, and casually looked back to see him right behind me, looking at me, and I looked straight at his angry face. I just jumped a little, turned back around, and walked into my house a minute later. Very, very strange.
