The significance of 11:11

My girlfriends lucky numbers, or number, is 444. Since learning this, I seem to notice these numbers in more and more places, which prompts me to think of her, but also the significance of these occurences. Little did I know, this phenomenom is actually called something : apophenia which can be defined as applying meaning to random data. Supposedly, it feeds on itself, which helps me explain why I see this number more and more. I'm not sure the whole point of this post, except to say that, if you keep seeing the same number over and over, and you can't figure out why, there's a good chance, this will help explain it.
