The Hidden Meaning

....There is a certain phenomina that has been happening to me for approximently the last year. And I mind you, I'm not a superstitious person by any means. I had to ask a friend about it, and he too, was having the same problem. The problem is repetitive numbers. I often wake to a clock that says 4:44, or i'll see my milage on my car at 1,111.1 miles. The other day, while I was biking, I almost lost it, and I noticed that the milage on the bike was at 999 miles. What does this mean? Is there something more to repetitive numbers? Is there really a hidden meaning in all this, or is this just something pyschological?
