If you want to divide a room, simply bring up the topic of ghosts.

There are loads of sceptics out there (me being one of them) who have never witnessed anything supernatural, but what if you're job was to deal with this field on a regular basis?

Gavin Canavan has been a demonologist for the past 10 years and with a recent spike in paranormal activity being reported during the heatwave, who better to ask about it?

Dermot and Dave gave the Wicklow man a call to find out why "the weather is such an important factor is spiritual manifestation". 

He's seen some crazy stuff over the years and offers his services for free, "when people have problems in their house - they call me". 

Whether you're a believer or not, he does making a compelling case with all he has witnessed.
