I was about 13-15 years old. We've just moved and just got stuff unpacked after a couple of months of not having it.

Settling in was fine. We had these huge windows that led outside. The view was... okay. But the house was beautiful. And! We had a pool! (We rarely used it, I'd also had to maintain it)

My sister's and I slept downstairs while my parents slept upstairs. Each sibling, of course, had our own room.

So, me being downstairs, I wanted to go talk to my mom about something.

As I was heading upstairs, I could hear the Tv going, which meant my Dad was in the living room.

Reaching the top room, I was about to start walking towards my parents room when I looked ahead and froze.

There was a Demon? Ghost?? It was a girl I don't recognize. It wasn't facing me. She was, what looked like, looking at the Tv or maybe she was just facing the living room?

She had long black hair covering her face, so I couldn't see it. A White-ish, Gray-ish dress, Grey skin.

It was unnerving. I didn't want to call out. So, I quietly and quickly passed her, keeping an eye on her when I did.

I never saw her again after that.

(This still gives me chills thinking about it)
