Dream of eyes

When I was about 5 or 6 and my little brother was about 4 or 5, we were playing at our grandma's house. Everyday she would go to hang the clothes she had washed on the clothes line and there was this big window in her room where we could watch her do it. So we're in her room and she tells us that she is about to go outside and hang up the clothes. So we hear her go out the back door and she starts to hang up something and she suddenly stops and she just stands there. A few seconds later, she turns around, almost like a statue, it was weird, and she looks at us. Her eyes were blood red and glowing! She didn't say or do anything, just looked at us. My brother and I heard a noise coming from the next room over, it was a bang; we turn our heads to the sound for one second, we look back out the window and she's gone. A few seconds later my grandma walks out of the room and we asked her if she had gone outside and she said, "No."
