FREAKING OUT

My cat was meowing and came to my bedroom door. I ask my cat what is wrong and she drops a live mouse out of her mouth to the entrance to my bedroom. The mouse runs away and the cat goes to catch it. I then call my parents to get out of their room and tell them that there is a mouse in our house on the loose. I have now baracaded my closed door with towels and boxes while my step dad spent 10 minutes stomping on a towel with his feet because he saw the mouse run under there. He picked up the towel. There was no mouse. We now have a mouse on the loose in my house, my room is baracaded with me inside it and im not leaving my room until tomorrow morning to go to school. My cat still hasn't caught the mouse again. And i'm not leaving my room till morning. Im scared... :(
