This is a film that starts off about a young girl who has a releatively mundane life but things change when she makes a new friend and go on a trip. The friend, although outgoing and fun commits several murders but eventually turns out to be an imaginary friend that was the young girls alter ego.

Unfortunately not. Not such a scary movie, more just trying to work out quite what/why it is happening. Thanks.
It is quite a new film, at least with in the last 10 years.
Is is typically British, but with an “Indie” look and carefully selected scenes, eg: English countyside, a caravan park and houses with specific architechture – some modern, some typical UK 70s.
