I have always been interested in ghosts. I'm not psychic but I can, for instance, pick up on the mood of a building. A nice place gives you a butterfly feeling; a bad place makes you want to back out. When I am working with an investigating group, we split up, go into different rooms. People might set up temperature experiments or they'll leave an object in a room with cameras on it to see if it moves. Things do happen. I've got pictures of orbs. There are many explanations for orbs but still, it's a good feeling.

Investigating the paranormal is always exciting. The adrenaline is pumping around your body but you're frozen, can't move. I love being scared. Over the course of an investigation I'll go through a whole range of emotions. One moment I'll be incredibly frightened, standing in a dark room; the next I'm ecstatic, thinking I've got some evidence. In Derby Gaol I felt the gaoler standing behind me. I was rooted to the spot. What could be better?

Paranormal work can bring happiness, especially if you are working with those who believe. Happiness is trusting your team. If there's no trust, the evidence means nothing. You're in a pitch black room and someone says, "If there's anyone here, tap twice." You have to know the others aren't tapping.

In paranormal work you can't base your happiness on results because nine times out of 10 you don't find anything. But the evidence will come, I don't doubt it.
