One Direction often have dreams about not carving a career out of music and instead being back at school.
The group - who found fame on 'The X Factor' 2010 - have been having nightmares that they are studying and their huge success with music mogul Simon Cowell, never happened.
Harry Styles said: "I had a dream that I woke up in maths like that. I've never had a dream where I felt famous."
He's not the only one in the band - which includes, Zayn Malik, Louis Tomlinson and Niall Horan - to experience the surreal scenarios of being a student again while they are sleeping.
Liam Payne admitted that he also finds himself dreaming of being a fellow pupil and sometimes finds he isn't wearing any clothing.
He told The Sun newspaper: "I dream of being back at school a lot and have been naked a few times. And I have been in the park naked on a climbing frame."
It recently emerged that Harry has been reading a dating manual to boost his sex appeal.
The heartthrob has been getting tips from self-help book 'The Game: Penetrating the Secret Society of Pickup Artists' on fellow 'X Factor' contestant Olly Murs' recommendation in the hopes of making himself even more popular with the ladies.
