Ask if it is possible to believe in the existence of ghosts, even now, in the twenty-first century.
Ask, on the other hand, if the quality of our lives renders our awareness of such problematic things as wandering spirits possible.
If the natural world escapes our notice, the phases of the moon, the turning of the tides, the subtle dynamics of the progress of the seasons, such that most of our perceptions are attuned to artificial environments and representations of "reality", how likely is it that anything other than the mundane to which we are acclimated can even capture our attention?
Noise, blinding brightness and frenetic activity being the norm, who can see into the quiet, still shadows?
