I think numbers can have significance for people who seek out patterns and connections among things. Number 3 is a good number for me, as I often recheck things three times or in multiples of three. The number 1111 shows up a lot. I remember when big bang theory first aired, thinking it a strange coincidence that Sheldon also used groups of three. I also feel like specific numbers can sometimes show up depending on how close you are to your true path.
