I keep hearing someone call my name?

For some reason or another I hear someone say my name or something very similar to. It's always been in the house, and we move a lot. This one time - I was all alone in the house and I literally heard someone say my name like they were right next to me, I freaked the fck out and just turned on the tv. Is it just me or is it something that's following me around or something? Because it's happened numerous times and I go to my parents and go "did you call me?" and they say no. WTF is going on,
