'It’s a bitterly cold night tonight and the air in my bedroom cuts at my face. I have no idea what the time is the night is so dark, so completely black for so long. But I had been asleep, and had now probably been awake for 3 minutes. You are next to me, and I think you realise I have woken up, half conscious you turn and ask me ‘what’s wrong?’

I fumble to explain ‘I’m worried about an asteroid hitting the earth, that it’ll happen while we’re sleeping and will have a moment of sudden heat and agony and then everything would be gone. Can’t you hear that whirring, don’t you think that’s the sound of an asteroid coming towards us.’

‘You’re ridiculous Dais, go to sleep, even if it was going to hit us you’d know years in advance and there’s nothing you could do.’
