So awhile back, during an ill advised marriage, my grandpa bought a cabin a few towns over from his hometown, out in the woods.
The place needs a fair bit of work, which he's been slowly doing since the divorce.
We usually stay with him when we visit nowadays, because my hypochondriac cousin kicks us out the second my sibling looks like they might be sick, and my great aunt seems to hate us.
We usually bring the dogs with us, because they love Grandpa.
Well, once visit a couple years ago, late at night, I'm taking my dogs out and as I look out to the woods at the back of his property, I see this greenish glow.
My first thought was maybe some drunk rednecks were just wandering around in the woods and ended up on his property. It happens. But as I looked more intently, I noticed that there was no person attached to the glow, as it bobbed around in the woods
And it was far too big to be just a firefly or something.
I watched for a couple minutes, in silence, til my dogs started barking at it...and it started moving closer.
Well, at that I turned and RAN, pulling my pups behind me, and locked the door tightly behind me.
The back door is all glass, flanked by too big windows, so I sat & watched until the light just. Disappeared.
No idea what the hell that was. Not real sure I wanna know.
(grandpa thinks it was aliens.)
