Oh Don, the world is not so boring as your lack of imagination would make it seem to you. Perhaps you are not aware of this, but people outside of your world actually do experience plenty of thrills and excitement without doubting easy facts such as that human beings went to the moon.
And I think comatose is best used on someone who cannot see those facts, and who is instead locked up in a world that borders on the solipsist. Reality isn't boring. A person locked up in his own reality is boring. A person locked up in his own reality atrophies, not a person in contact with the world.
