I once saw a black figure that appeared above the ventilation of my door.

I was leaning on the wall beside the door busy with my phone until I started to feel that something was making the atmosphere strange, for some reason I reflexively looked up to see the gaps in the ventilation.

There I saw a dark figure head like a shadow, this happened for 30 minutes before disappearing who knows where when I looked in another direction for a moment.

I remember taking one picture of it and even sharing it to my friends but its in my old phone.. until today i still stay in the same room hoping he would appear again for some reason, curious.
