Logical similarities or strange coincidence?

This concerns me and a friend. We have very similar interests and have even made similar life choices despite only recently getting back into contact with each other after almost 6 years apart. Our birthdays are 2 weeks apart, born in the same year. Both moved to the same area about age 13, met at a summer camp related to a school program. I attended 3 different high schools but every school year I had at the very least 1 class with him, ,at most 3. Due to the decisions of our mothers we both had to leave home and depend on others to help us on our feet. Our interests are very similar, the career we both would like are in the same field, our hobbies line up, our food choices are even the same. A lot of likes came about in the period when we weren't in contact. And while we have similarities there are exact opposites. We both aspired to the military but i made a choice not to go. He went to college, I didn't for other reasons. Both of our significant others are red-haired blue-eyed. His woman is underweight, whereas my husband is overweight. We both have brown hair and brown eyes. We both share very similar views on theology and philosophy. Even worked and wanted to work similar jobs. Me at IHOP him at Waffle House, both tried to be bartenders at 20. Also the same reoccurring dream for about 3 years. He described his dream to me and I showed him mine in my dream journal. So alike at times we could almost be twins. Our bloodlines even coincide to a degree, though I can lay claim to origins on 2 more continents. Ancestry is a different story, He can trace his, I cannot I am a first generation American with unreliable source to ask about mine. I often wonder if its a statistical inevitability or if its something deeper, a connection on a whole other plane of existence.
