The number 37?

The number 37 keeps coming up with my sister and me. I ride the bus number 37. I was in the ER at a hospital Wednesday to Thursday and my room number was 37. My sister had a dream that her boyfriend was in a car accident at _:37 and looked at the clock at _:37 and that day at _ :37 he was in a car accident. The number keeps reappearing whether she or I looks at the clock. What does this mean?
