Reminds me of a Star Trek episode, where devices were implanted in Kirk's brain and somebody else's (I can't remember the character), and they were forced into an empathic symbiosis; so close that they couldn't even be more than a few feet apart from each other within experiencing extreme physical pain.
And the thoughts they "saw" in each other...my oh my, if we each had even just one minute of that kind of unadulterated unedited untranslated bared-soul honesty with each other!
Telepathy is an intriguing idea, but I daresay it would scare the poopy-doodles out of all of us.
