Steven Moffat revealed on twitter he based the Veil on a dream his son told him about.

"My son, Joshua, told me about a dream he had: there was tiny slug-like creature somewhere in the world. It was very far away and very slow, but it was inching closer to him all the time, and when it finally arrived he knew it would kill him. The origin of Veil. #hellofabird"

I'm a bit confused since that sounds exactly like a premise told on the Rooster Teeth Podcast, which came out more than a year earlier. The Podcast came out on Aug 26, 2014, the idea was made into an animated short that came out on October 1st, 2014.

The Doctor Who episode aired on November 28th, 2015 (no idea when it was written though)
