How would you feel about micro-filaments being inserted through your skull so I can run a long-term brain study when you sleep and have these dreams?
Or perhaps I can interest you in simply giving me your grey matter on a silver platter.
I assure you that I will use the proper anesthetics. Or that I won't remove any of your other organs and replace them with baboon-based substitutes. It shouldn't be noticeable in the least.
