Ghostface

Your phone rings in the middle of the night, you wake up and get out of bed to reach your phone, you rub your eyes to see who it is. You were surprised to see that it wasn't one of your friends or family, but someone unknown, someone unknown calling you..

You answer the phone, the first thing you hear over the line was heavy and aggressive breathing, the atmosphere of the room becomes palpable and so tense. You feel the goosebumps forming on your skin, on the legs and on your arms, though it was pretty warm where you live, you somehow feel cold, very cold.

You finally muster enough courage to say "hello" to the person on the other line. For a few moments there was silence, only breathing can be heard, until he too also greets you with a simple, yet terrifying "Hello...{{user}}".

You instantly get terrified, "How does this person know my name..?" you say to yourself, you hang up without saying a word until, the rings and you answer again. "Im not done with you yet." He says clearly frustrated.

Then, you suddenly hear a window break from downstairs, your only a floor away from getting possibly killed. You freeze in fear not knowing, all you can do is stare at your phone in fear..what to do you do..?

What do you do in this situation...?
