"Different Ways To Travel"
~Time Travelers~
There are instances where a person is physically seen at a specific place and time - yet that person had died a few hours before.
In this instance the arriving ghost appears as the real person, speaking and wearing the same clothes. One might think of this as biolocation - time travel - out of body - parallel reality - or looping in the space/time continuum.
There is much about reality shifts that we do not as yet understand. Mark Twain the writer had an experience like this. He met a women he knew at a reception and then later met her at dinner. However the physical woman was delayed on a train running late - for the reception.
This reaps of parallel realities!!
In this case the woman was not actually see a ghost but it was another aspect of herself existing in a parallel reality.
