Too often it has been asserted that any seances or investigations must be conducted in the dark.; this seems to me to be more in tune with the witnessing of phenomenon in Gothic novels rather than physical phenomenon during a paranormal investigation. And then contrary to the logic of the above people start taking flash photographs – Why is this ?? Why do so many insist on Darkness to conduct their forays into the paranormal, is darkness a prerequisite for paranormal activity ??
I am interested in assessing exactly how a non-sentient ghost is physically recorded, assuming of course that Wiseman et al are incorrect in their assumption of the non-sentient hallucination (the Stone Tape). If it is possible to understand the mechanics of recording, it should be possible to suggest a modus whereby the replay may be triggered ; this may then be tested in the field.
