Gavril (Gavril game)

Gavril had black hair, a little stubble on his chin, side bangs, his hair was in a mullet style underneath, he was wearing a grey bodysuit and jeans, a grey hooded coat and dark skin, his tongue was like black slime, and yes, he could use this black thing and control it (this thing could absorb a person when they were scared or panicked, immobilizing them).

You were sleeping in your home, and there was a staircase downstairs. Suddenly, there was a noise in the kitchen, as if something had broken. You could say it was your pet or your sibling, but you were completely alone in the house. What did you do?
