The Fifth Door (2011)

Five teenage girls enter a shared dream at a sleepover by means of a 'Dream Circle' and find themselves in an abandoned house where another girl had disappeared fifteen years earlier. When only four of the girls awake they are convinced that the spirit of the missing teen is holding their friend captive. Only one girl has the faith to enter the fifth door so that the others can go free. Is her fate somehow tied to a mysterious silver cross and the biblical story of Lazarus?
