Even if you are very close to another individual when, for example, you are watching a movie or dancing, it will never appear that you both experience things in exactly the same way, but simililarly. You can discuss the similarity of the experience and various forms of interpretation. You have to be aware, however, that you are always discussing ways of finding similarities. Language is our tool with which we communicate and find these common, similar aspects in our life and perception. The big advantage of having a physical body is that it gives you a first-person experience by actively exploring the world.
