I have just joined and have a lot of stories to share; some are not so long, so some of my posts will have a couple of stories just to meet the required 1500 characters.
I was standing behind the counter in the spiritual bookstore I worked in for eight years some years ago. The counter faced the entrance to the store, with a few steps leading up from street level.
It was a rather busy time of the day, so we were three clerks behind the counter. Suddenly I noticed a man coming up the stairs, casually dressed, walking normally, looking down in front of him. When he reached the top of the stairs, 8 feet from where I was standing, he lifted his face and looked at me - and I stared into the blackest blackness in his eyes. I didn't just get chills, my heart skipped a beat. I felt as if the air was knocked out of me and I turned my back to him, but in that same moment, I was sure that he would jump the counter and go for my throat, either with his hands or his teeth, so I ran out from behind the counter, right through the store and up into the back office where I stayed for a long time, until I was sure he'd left.
It was really a strong feeling, I'm positive I wouldn't be here today, if I hadn't ran away. I don't know why, but that man or whatever he was, was out to get me. Luckily, I haven't encountered other black eyed beings since then.
Having read through some of the stories here, I can see that it's common that it's kids that have black eyes, but this was a fully grown man. He didn't get to talk to me, but the feelings described by those who have seen the kids, are pretty much the same as mine.
