Doors opened and closed, the room went very cold and Steve felt, "there was a strong sense of presence".
In addition to the programme, the group has also been carrying out its own investigations at the castle. For this work, they use computerised monitoring equipment which measures changes in the atmosphere, traditionally associated with paranormal activity, such as temperature, ionising radiation, humidity, light and electro-magnetic radiation.
Parascience was keen to see whether this happened outside strict laboratory conditions and they have conducted research at a number of locations, including the farmhouse, occupied bya father, mother and three children, two of them teenagers, all of whom were complaining of ghostly experiences.
Ordinary electrical appliances give off electro-magnetic waves without affecting most people in any discernible way.
But the 18-strong Parascience group had been working on the basis that in places, where there is an unusually high concentration of electricity, there will be an increase of paranormal goings-on.
In the farm, the electro-magnetic radiation was measured at more than 50 times the average domestic rate. This was traced to mains electricity cables tied to the gutter-boarding.
The cables were repaired relocated by the electricity board and the incidence of strange happenings dropped sharply.
Now, to add to their research, Parascience is inviting people to take part in a survey by answering a series of questions on their website. www.parascience.org.uk
