Replying to What the fuck, man.

Hello NS. I am a little freaked out right now. I was heading up my stairs from my room which is located in the basement (I had to take a rather large shit and my toliet down in my basement doesn't work properly) and as soon as I turn the corner to venture across my kitchen and into the upstair bathroom, I see what appeared to be a black shape that looked like the shape of a human move very fast across the hall from the bathroom into our dining room.

TL;DR I witnessed a ghost in my house and I am kind of scared.
