Charlotte Ritchie believes the 'Call The Midwife' set is haunted.
The 25-year-old actress - who joined the BBC One period drama for the current fourth series - couldn't bear to go to the toilet on her own while filming at Nonnatus House because she is convinced there are ghosts there.
She confessed: "I can't go in there alone.
"When you go in you get this strange feeling that you're not alone. It's so spooky and surreal."
The former 'Fresh Meat' star - who plays Barbara Gilbert - admitted she isn't the only one who has noticed strange goings-on, with other people involved in the show hearing voices when in other parts of the building in Surrey, south east England.
She explained: "The props guys told me they heard voices in the attic room when there was no one else up there. One came down and he was properly white."
However, Charlotte revealed she has always felt uneasy when it comes to the supernatural and feels like the beings impact her whole life.
She continued: "Poltergeists really get me. I had a dream last night about a ghost. It's not a question of belief - whether it's true or not it definitely affects my life."
And while she admits the ghosts have scared her on set, she confessed she gets freaked out easily, even by watching TV such as 'Doctor Who' and 'Breaking Bad'.
She told the Daily Mirror newspaper: "I find 'Doctor Who' really frightening. I'm a total scaredy cat.
"For example, I've tried to watch 'Breaking Bad' three times but because I watch it late at night it really traumatizes me.
"I already have really weird dreams so I don't want to make it any worse."
