I'm not sure I should admit this

My alarm has been scaring me in the mornings. That is, every morning it goes off, for at least the past week. It doesn't matter if I was briefly awake 15 minutes prior to it going off, it will still scare me. Sure, the fear only lasts for a brief moment, only until I realize that I'm at home, in my bed, and that my alarm clock is making all that awful noise. Still, I never had this problem before. What's up with that?
