OK, I'm not crazy, this could really happen! Telepathy between humans could be possible using technology.
Nanobots can be used to analyse brainwaves and combine the signals into a coherent speech pattern.
The speech pattern can then be transmitted by radio frequency (RF) to another human who's Nanobots pick up the signal and 'broadcast' the signal into the receiver's eardrum, or even directly into the brain.
Not only can the Nanobots analyse speech within a human's mind, transmit that speech to another human, but with similarly advanced technology, the speech can be instantly converted into a different language too.
Have you ever had an idea or image in mind but can't express it with words? Your Nanobots could analyse signals in your brain to construct a picture and transmit it to a monitor for anyone to view and even record.
