  Okay, here's my recreation of the trick Derren Brown used last night to see if the participants could 'sense' which 'spirit' they were talking to. Right, all these people are dead, but one of them is trying to communicate with you. Study the pictures for a while.
One of the colour photos should be attracting you. Focus on the colour photo, and try and get an idea of their personality. Now, start looking left and right. A black and white image should now be attracting you. Focus on this black and white phot, and try and think of a word which was important to them. Looking up and down, another colour photo should be getting you attention. Focus on it for a while.
Hold your breath. Now look diagonally in any direction from the colour picture and one of the black and white pictures should stand out. Breathe out once you can feel it. The spirit's pull is getting stronger, keep looking left and right, left and right, until you have one of the colour photos in your mind. Focus on it. Read the name. Was Linda calling out to you?
