Freely in space and time

It is often said that the patient who suffers from dementia lives in the world of ‘here and now.’ As far as my father is concerned this is not necessarily true. One mornig my father surprised me by saying abruptly that he would go to a barber to have his hair cut. It seemed that he had forgotten that he could not walk without the help of others. I should not have stopped him then but I coujld not help asking him how he would go. ‘Not so far. Walk.’ He answered flatly. He must have been living . He was in the past when he could do anything though come to think of it I am moving freely to and fro in space and time while I am thinking. The difference is that I can come to this real world while he cannot be back easily.
