The Panic Room meets two more people with extreme phobias as the series continues. The rooms have been specially designed by two leading psychologists to treat these people.

Chris Soutar, 23, a sales manager from Great Dunmow, Essex, has a phobia of lifts and hasn’t been in one for years. At the age of 10 he was stuck in a lift and thinks his phobia may have developed as a result. His worst nightmare would be to be stuck in a lift by himself.

Psychologist Lucy Atcheson treats Chris by exposing him gradually to his fear. He enters the Panic Room on day one and takes a virtual lift ride. On day two, he crawls through a tight dark tunnel, and on day three, he faces his worst fear when he’s asked to take a lift to the 23rd floor.

Emma Chapman, a 21-year-old single mum from Croydon, works as a pensions administrator and is terrified of spiders. Psychologist Felix Economakis takes Gemma through a course of hypnotherapy and graded exposure.

On day one, Gemma views pictures and video footage of spiders, on day two she faces a live house spider and on day three, she is faced with a Chilean rose tarantula.
