Rowling said, "It was the publisher's idea, they could have called me Enid Snodgrass. I just wanted it [the book] published."

She based the character of Hermoine on herself

Rowling's clinical depression inspired the creation of Dementors

At the age of 25, Rowling became a single mother to daughter Jessica after a short and "catastrophic" marriage. She said, "It hit me what a complete mess I had made of my life" she said. We were as skint as you can be, without being homeless, in other words we were existing entirely on benefits. And at that point I was definitely clinically depressed."

"It's so difficult to describe [depression] to someone who's never been there, because it's not sadness," Rowling told Oprah in a televised interview. "I know sadness.

Sadness is to cry and to feel. But it's that cold absence of feeling - that really hollowed-out feeling. That's what Dementors are," she said of the cloaked creatures which feed on happiness in the Harry Potter series.

"My heart is divided three ways: Harry Potter and the Philosopher’s Stone, Harry Potter and the Deathly Hallows and The Casual Vacancy," she said.

"Because I promised my editor I wouldn't." When asked if she feels she's missing out, she replied "Not wildly".

"I had a lot of fun making up the rules and I've still got the notebook I did it in, complete with diagrams, and all the names for the balls I tried before I settled on Snitch, Bludgers, and Quaffle."

In a recent interview, Rowling said she dreamed she met Dumbledore three nights prior.

"I didn't often dream about it (Harry Potter) when I was writing it.

It was so in my conscious mind that at night I didn't need to.

But I've had a few dreams since I stopped writing (Harry Potter). It seems to be living at the back of my brain again"
