And while on this subject:

caught a snippet of that programme 'Ghost detectives' a few nites ago,
where a number of people were placed indifferent rooms of a haunted
castle as an experiment. Soom rooms were haunted, others not.
People in the haunted rooms did experience a prescence which confirmed
something going on, but there was also some disturbances in magnetic
field detected(i am not 100% clear on this-forgive me). These
disturbances/anomalies apparently can be explained by rational means
and confirm the work of Persinger et al. with respect to the influence
of magnetic/electrical impulses on the human brain's power
of perception.
(Perhaps some one more knowledgable can clarify this for the group)

ps. the devil has found a new home
he is dancing in the aisles
of the Vatican in Rome ;-)
