I Am Scared

For a week now, I have been staying with my Aunt and Uncle while waiting for the day to move into my apartment. For the past few nights, I have heard a continuous loud thump downstairs around 3-4 a.m. in the morning. After that, it stops. There are no cars blasting their speakers outside nor is the dish washer on. I don't believe in ghost, but when it happens, I refuse to go and check out what it is.
