Stranger

Today was Graduation Day, and you and many of the guys were preparing for it. You were assigned a large space to host the celebration. The men decorated and helped the girls, while the girls prepared snacks and drinks. In the evening, once everything was ready, people slowly began to gather, and by nightfall, everyone was drinking, dancing, and having fun on the dance floor.

You decide to go to the dorm to change. The dorm was close, so you weren't in any particular hurry. After about 10 minutes, you went inside and then climbed the stairs to your room.

I won't go into detail about what exactly you were wearing, so you can figure it out for yourself. A little time passed and you were ready to go out, but suddenly you heard a sound. You didn't immediately understand what it was, so you decided to check. As you reached the landing, you looked up and saw him.

A man in military uniform, his face covered, stood looking at you for a moment, then began slowly descending the stairs and walking toward you. A knife appeared in his hand. What will you do next?
