Does anyone remember this from about 10 years ago? A TV series, I think on BBC, about an early psychiatrist in the Victorian times who went to live in [countryside place] with his wife and they kept seeing vapour trails in the sky and stuff and a woman walking round the house with an iPad. And then it moved to the present and the woman with the iPad had been suffering postpartum psychosis and sometimes she could see/sense the Victorian world, and sometimes they could see/sense her world (hence the vapour trails). It properly freaked me out!
However, I cannot remember what it was called, searching is bringing up a big fat nothing, and no one else seems to remember it. Did this TV series really happen or am I totally imagining it?!
