Not so few people have experienced synchronicities or telepathic phenomena. Does this mean that your mind is not confined to inside your skull?
Your eyes detect photons, and your ears detect waves in the air, but what part of you detects telepathic signals? And what is a telepathic signal?
Are we connected somehow, also without telephones or the Internet?
What if some of your thoughts and emotions are not created in your brain?
What if all of your thoughts and emotions are created somewhere outside of you? The brain may be some kind of receiver, some speculate.
Why do so many stupid, silly, and nasty thoughts arise in the brain? Have someone hacked our minds?
