The term/s open/ed, close/d mind/ed are not meaningfully defined concepts. Rationality is achieved through the exercise of an active mind, i.e. a mind which actively seeks to discern reality from fantasy, truth from delusion, the correlation between what it believes and what is real.
'Ghosts" are equally undefined constructs of a mind that does not find meaning an essential precondition to understanding and differentiating reality from delusion. If we choose for a definition of �ghosts�, �entities of disembodied consciousness", the concept quickly vaporizes into the oblivion of preconceived ideas from which it came. Consciousness proceeds from the physical action of a thinking brain and when the brain dies the faculty of consciousness dies with it. If you require proof of this, or wish to prove me wrong, open your skull and extract your brain and then tell me that I am "open/ed, close/d mind/ed"!
Just so you know I am not totally "close/d mind/ed", I do agree with the "Spooky" part.
