What's the creepiest thing you've ever experienced?

I was driving down a long, straight backroad one evening after a late shift. It was dark but could see a mile ahead with the headlights, it was so clear and nice out. I see in the distance a woman walking on the side of the road in a dress and heeled shoes. Nothing fancy, just like a dress one would wear to work. And she's walking in the opposite direction. The thing is I only really saw her lower half because of the angle of the lights. But I kept an eye out for her so I could give her space and maybe slow down and see if she was ok.

As my vehicle passed her and she left my headlights, I lost sight of her immediately. I came to a complete stop, looked around like a madman, but I could not see her anywhere. I looped around back in my car and drove a mile up and down that road a few times. There were no bushes or ditches for her to have hidden in. It's like the moment she left the light, she vanished, and again I never saw anything but the legs.

One time when I was probably 8 or 9 my neighbors had this outside dog. It went in sometimes, but slept outside. But one night they left a window unlocked, and they had a Sega Genesis, so I climbed through the window to play. The dad woke up so I bolted up the stairs into some kid's room, and went to dive under the bed, but this kid just starts PETTING me. I didn't know what to do I just licked their hand. Spent the whole night in fear until finally getting the courage to sneak back out.

So this happened to me one time when I was about 8 or 9 years old. My brother and I shared a room upstairs at my dad’s place. At this house, we had a family dog who was predominantly an outdoor dog who rarely came inside and certainly was never allowed to sleep inside.

One time, at the dead of night, I woke up to hearing footsteps that sounded like my dog quickly running up the stairs. Being tired and young, I just assumed my father had let the dog inside the house. However, I could not see what it was since it was extremely dark in the room. But anyways, I pet it and it licked my hand. I then heard it run to my brother’s bedside and he woke up to pet it too. Soon after, it ran down the stairs and left.

Fast-forward to the morning, my brother and I were eating breakfast with our dad. As we all chatted, I asked dad why he let the dog in over night. He responded by saying: “I didn’t let the dog in the house and noted how the doors were all locked.” (which made sense as my dad religiously locks doors). I told him about what happened: he said it must have been a dream. My brother interjected saying: “I experienced it too.” My dad’s face dropped and he became visibly freaked out.

To this day, I have zero explanation for what occurred that night and what thing I pet. It's easily the creepiest experience I can recall.

Edit: fix

I haven't had anything creepy happen to me personally that I can recall, but I do have something that did terrify me for a bit.

This was around a year ago but I was in the bathroom washing my hands after using the bathroom, this was very late at night, about 2:00am. That's when I heard some sort of noise that caught my interest. I was wearing noise-cancelling headphones so I was surprised that I heard this. I took them off and heard nothing afterwards, so I just chalked it up to my mind playing tricks and went back to my bedroom.

However, the sound did sit with me. It's one of those sounds that is engraved in your intuition. So I went to check the camera footage around the time that I heard the sound. I went back a couple of minutes and played back the footage, waiting to hear anything. After going through a few minutes, I was ready to give up on it, since it was just wind noise and distant traffic. That's when I heard this absolutely most long horrific blood curdling scream that I have ever heard in my life. It sounded like a woman and it genuinely made me freeze for a good few seconds.

I was in absolute shock and didn't know what to do about it. I sent it to the local police station and they said they'll investigate to see if anything came up around that time. I checked the news for a few days after in the local area and nothing about a murder or domestic violence incident came up. This area is usually pretty safe, so it was definitely a shock.
