Seeing Repeating Numbers? What do they mean?

This happened with me as well. I started seeing repeating number 1111 in billboards, vehicle number plates, and phone numbers and in some random locations. My initial thought about it was ‘what the heck with these superstitious people’. However, it was not very late the 11:11 started appearing on my digital wrist watch, on computer system tray clock, on my mobile and many other places.
