I think there's a ghost in my house

I keep seeing something in the corner of my eye only at home now am afraid I heard something say my name and I am home alone because my parents are out my brother is at his friend's I rushed out of the house with my cat and laptop because I couldn't leave them in their and I was wearing short shorts and had to go pee really bad so I ran to friends house with my cat and now I don't know what to do and it's dark
