This is a "Hey guys" story, but not about the hey guys guy. You'll be surprised.
I take out the trash. I hear a ghostly voice saying, "Hi..." I look into the backyard and see nothing. It's a dark night. I turn around to roll the trash can to the front. I hear it again, and this time, lightning flashes, and I see my dog, Lexi, standing there. It goes dark again, and I run as she chases me. Then I wake up from my nightmare.
