Do some people have natural unspoken connections with others?

I have this weird thing with my best friend, where we know what the other one is thinking just by looking at them (it's common between people who are close to each other), but we also have had many coincidences in our lives even before we met each other. We also sometimes feel what the other one is feeling without even knowing what the other is doing. kinda like twins, you know? I believe he is my soulmate.
