Worst nightmares can also appear with your eyes open.

I'm pretty obsessed with Stevie Nicks from her style to her voice. I like watching her on YouTube and her old performances, the way she moves and everything.

I've got quite a vivid imagination and I'm easily overwhelmed by sensations and things that are beautiful or scary. I don't think I've ever seen a ghost - I think I'm probably haunted by my own ghosts than real ones.

Music to me is so internal. It's physical and it's emotional. Whereas fashion is so much about the external that it's almost like a break. It's not inner turmoil. It's total escapism.

When I'm singing I'm always trying to get to the highest point possible. I'd fly to the top of Buckingham Palace to sing to the queen.

The stage is the place I feel comfortable - it's almost as if real life is where I feel most nervous. Conversations are a lot more nerve-wracking.

I've been having this really weird anxiety dream about arriving too late or too early, and the people in charge are like, 'You have to leave! You have to go back to the hotel and get ready!' And I use the wrong exit, and I'm running down the red carpet in ­pyjamas, like, 'No! Don't look at me!'
