soooo
going back to the vibration thing. Its proven that everything on the earth has a vibration frequency, so if the brain interprets these vibrations
(from sensors eg eyes, nose, ear) it should be possible for us to attach extra sensors and use the brain to see "infra red" or radio waves.
Its also very possible that we have lost these abilities through lack of use.
This would also explain alot of
sick building syndrome cases also.
