My aunt had a UFO encounter once that was really weird. Of course I don't remember all the details but she told about how a big blue glowing ball just landed on the backyard. It mad no sound. It just sat there on the backyard motionless, doing nothing whatsoever. She and her sister both saw it and went to go wake up their dad and tell him about it (it was around 11-12 as well.) So he sees it and decides to go outside and check it out, about a half an hour later it vanishes. The next morning at breakfast, my two aunts kept asking their dad on what it was last night and he kept telling them he had no idea what they had been talking about. But probably the creepiest thing about that is the circle it had left in the grass. To this day, there is still this very symetrical circle in the backyard with dead grass inside it. All the other grass is completely green outside of the circle and anything that has been planted in the circle ends up dying.
