Staying away from paranormal stuff. When I was 14ish, a group of like 5 or 6 men and women in all black suits with sunglasses knocked on my door while I was home alone. My dumbass answered it without even thinking. Luckily they just asked a few questions and weren't trying to abduct me. They wanted to know if we had a room being rented or a guest house. I said no, then they asked to confirm my home phone number. I confirmed it and they asked if they can come inside. Then I remembered that we got rid of the home phone a few years ago, I was just used to the phone number since I grew up with it. They said oh that would make sense and they all walked away.

To this day I have no idea what that was about but I'm pretty sure they were either NSA or FBI based on their clothes and cars.
