"Be Right Back," in which Hayley Atwell brings Domhnall Gleeson back from the dead using his social-media profile, sprang out of an unrelated conversation. Other stories you thrash away at for weeks and weeks.

I am neurotic, and I'm a worrier.

Seriously, if I switched on the TV and they were showing live footage of an army of fire-breathing pterodactyls machine-gunning people to death on the streets of London right outside my door, I'd be horrified, but not entirely surprised, nor any more scared than I already am. I'd probably just shrug and wait for them to smash the door down. We're so screwed, I don't even know what to worry about first.

Don't accuse anyone with the temerity to question your sad supernatural fantasies of having a 'closed mind' or being 'blind to possibilities'. A closed mind asks no questions, unthinkingly accepting that which it wants to believe. The blindness is all yours.

Am I living in a simulation?

I was more aware initially of shows like Tales of the Unexpected. And the BBC used to put on a lot of one-off, bizarre television plays.

I grew up in the countryside . But there's a danger of us romanticizing that. Because when I was a kid in 1982, that's what my parents were saying to me about television and comics and computer games!
