Do you think it is possible to have an unspoken connection?

I'm looking for opinions here. Do you think it's possible for a guy and a girl to have and/or feel an unspoken connection? In other words, do you think it's possible to have a connection where they can understand what the other means, wants to say, or even feels by simply looking each other in the eye or by observing each others' body language without actually saying anything? Why or why not? Have you ever experienced something like that?
