Harry Potter author JK Rowling has revealed the schoolboy wizard has started appearing in her dreams.The British writer is struggling to finish the seventh book in the fantasy series set at Hogwarts School of Witchcraft and has recently been dreaming she is Harry. Rowling revealed on her personal website: "For years people have asked me if I have ever dreamed I am 'in' Harry's world."The answer was no until a few nights ago when I had an epic dream in which I was, simultaneously, Harry and the narrator."As the narrator I knew exactly where what I needed to find was, while as Harry I was searching in all kinds of other places, while trying to make people around me say lines I had pre-arranged for them."The Harry Potter books have sold more than 300 million copies worldwide and have been translated into 63 languages and a lot of expectation rests on the 41-year-old author's shoulders to complete the final tome. She said: "I am now writing scenes I have planned for a dozen years."I feel alternately elated and overwrought. I both want, and don't want, to finish this book. But don't worry - I will."Rowling also revealed she recently saw a twenty minute preview of the fifth Harry Potter film, 'Harry Potter and the Order of the Phoenix', which she thought was "fantastic". She said she had visited the set to speak to the stars of the film and had chatted with actor Daniel Radcliffe, who plays Harry, about his theories on how the final book will conclude.
