There are a lot of strange tricks that people use to help them drift off to the land of nod.

Some people count sheep, others sing to themselves while others swear that a glass of milk does the trick.

English footballer Wayne Rooney has admitted a strange method that he uses to fall asleep when flying - he sleeps on the floor!

Rooney explained his looney behaviour to the London Sun newspaper saying he likes to hear the background buzz when he's trying to sleep.

"If we're on long-haul flights I've been known to sleep on the floor so I hear the engines. On occasions, when the manager has walked past he's asked what I'm doing"..

Rooney said that if he's sleeping by himself in a hotel, he puts the hairdryer on when he goes to bed.
