Why are their strong connections between two strangers?

I tend to think its when you share a lot of commons with a person that are communicated through body language and energy. If not a platonic 'connection' then its just a strong attraction or desire for more on a sexual level based on outer appearance.

In my life i have experienced the same feelings and those people that I have approached or gotten to know have turned out to be the best of friends. These feelings I deem to be a form of divine gift and embrace and explore them.
