Question about recurring sequence of numbers?

I have a wierd question about a recurring sequence of numbers that I'm always noticing around me and it has to do with my birthday but my birthday isn't really my birthday. I keep noticing the numbers 1007, I see it either in prices or on clock faces (whether it's a regular clock or digital) or on odd items in stores, at auctions,in all kinds of places and things. I was an adopted kid (I'm 52 now) and I found my birth mother, she claims I was born on the 10th of october which would be 1010, but I still keep seing 1007 all over the place and it just drives me bonkers.....I'm wondering if theres' any significance to this string of numbers or if I'm indeed "just freakin nuts". I've already spoken to a shrink about it and she just sluffed my observation off and said it was an obsessive subconcious thing and not to think about it (which I'm doing here) hahahahaha!!!!....I'm interested in hearing any ideas anybody has about observation theories.....I've heard about this kinda thing before but I didn't give it much wieght......So go ahead folks.
