A few years ago a feral cat gave birth to a kitten behind our garage. One night, soon after, the kitten was meowing incessantly. My brother and I figured the mom had abandoned it, so we decided to rescue the kitten. It was around 8 or 9pm... I'm not sure. But it was already dark outside. At the time, I was 20 y.o. and my brother was still in high school, though he was already about 6'2" and about 200 lbs. That particular day he wore a white top, white jeans, and white sneakers.
There were no lights in or around the garage so we were just staring into slight darkness calling the kitten. At one point my brother stepped inside the house. A few minutes later, I spotted the kitten. I didn't want to lose sight of it so I kept my eyes on him/her. I yelled out for my brother but got no response. I yelled out his name a few more times and nothing. I finally looked over to where I saw his big figure (his all-white-clad figure) but he hurriedly walked around the side of the garage; fast enough that I only saw the big white blur of his outfit. I didn't know where he was going, so I went after him. The lights of the house lit up the yard just enough to see a bit.
I looked around the side of the garage, and again his white blur quickly went *behind* the garage where it was pitch black. Absolutely no light. I went after him but I didn't see him in the darkness. So I yelled out his name. From INSIDE the HOUSE, my brother yelled "what do you want?!"
The whole time he was inside the house! That was too much! I just ran into the house way too freaked to come out again. I still don't know what it was I saw.
I have other stories about that house... Though none nearly as freaky as this one.
