This experience was very short but it was enough to stay in my memory for a long time. It happened when I was 14. And I'm 23 now so it was almost 10 years ago. I lived in Tennessee at the time.
While I was growing up I always shared a room with my younger sister, but when I became a teenager and needed my own space my parents decided to build another room for me. We started with an unfinished lower level of the house (not exactly a basement but lower than all the other rooms in the house) It was just concrete floors, and basically a home to the spiders and cobwebs, but after it was fixed up I couldn't believe it was the same space. It had two bedrooms and a tv room. I was pretty excited about it! I always had an intense fear of basements, like a lot of kids do, but I felt pretty good about this new space because my parents had gotten rid of the "creepy basement look." I thought it wouldn't turn creepy at all... But it did.
One night I was getting ready for bed and walking into my room. When I walked out of the tv room and into my room, I could see across the room, out the window, and into the yard, because it was not that low of a basement and because it was directly lined up with my door. My first glance in there was the window. We were still adjusting the curtain sizes so I think it fell off, and at that moment I didn't have a cover on the window. In a split second I looked, saw these strange eyes staring back at me right outside the window, I ran upstairs faster than the speed of light, locked the door and slept on the upstairs couch. In the morning my dad asked why I was on the couch and I was like... I don't even know how to explain what happened!
After that I used my room to do all the usual teenage things and hang out with my friends. But I didn't want to sleep down there. For a whole year I refused to sleep there, and slept on a futon in my sister's room instead. That probably sounds silly. But I was still freaked out! I only felt safe down there during the day. One reason it kept haunting my memory was because they were much bigger than normal eyes. It happened so fast that I wasn't sure if there was a whole face with it. All I noticed was the eyes because they were probably five times bigger than normal human eyes. But it still was the human eye. With the iris and pupil and everything. Just much bigger. Basically, it looked the way eyes would look if you saw them through a magnifying glass or something! I almost wish I would have looked longer, but my adrenaline sent my flying up the stairs!
I tried to blame it on my imagination but I don't think that's what it was. At no other time in my life did I see something like that. Even when I was afraid I was a pretty logical child and didn't like hallucinate or dream up figures in front of me. Plus I was wide awake, under bright lights, and didn't have any weird dreams going on or anything. I didn't see it again, but that could be because I stayed the hell away from my window after dark haha.
Was it a spirit? Some other entity? Is it possible that only a spirit's eyes would be visible? Cause I'm pretty sure it was a person looking back at me! (and I should make it clear that our land had a history of Civil War Battles)
