Why you might find your friends sleeping in a peculiar place this winter

A London homeless charity is asking the public to take a photograph of themselves sleeping in a weird place and post it on social media, as part of a viral campaign aimed at tackling homelessness.

Shelter from the Storm is asking Britons to take the pictures, donate to #Bedless and nominate at least three of their friends to do the same.

It follows the success viral campaigns such as the ice bucket challenge and the no make up selfie - and celebrities are already getting involved.
