I blame this one completely on reading too many scary detective novels at a young age. Some backstory about me, I live in a REALLY old house (which I'm pretty convinced is haunted by a ghost named Brian- but that doesn't matter) which makes loads of scary noises.
Anyway, every night I go to bed and wonder if I'll wake up the next morning. There have been times where I was positive that someone was in my house, and therefore I am absolutely terrified that I'm going to be killed in my sleep.
