If you are so much "in the know" about telepathy, then please explain how it works, since I would genuinely like to know.
By what physical means are the alien's thoughts turned into a transmittable signal?
By what process is the human mind able to both receive and translate that signal, and what area of the human brain is used for this process?
How are the aliens able to transmit the signal directly into the human brain without inducing a seizure or possibly a stroke?
You don't have to be very technical in your explanation, and even a theory would be appreciated.
