I saw the programme and loved it! Especially when Derren said that the mediums sister lived next door to the lady he had chosen to read for lol, some coicidence that was eh?
Derren is an artist, he does say he isn't psychic because to him a 'psychic' is a fortune teller or someone that sees the future, and those are what he doesn't believe in so to him being called a psychic is an insult.
Green Macaw just take it slow and keep practicing your aura reading, and slowly your confidence will improve and your readings get more accurate

Do you read pictures? That ios great practice
