Christmas is often a time to visit family and loved ones - but as we cram into family homes the lack of sleeping space can quickly become apparent.
Some on social media have been using the hashtag #DuvetKnowItsChrismas to share photos of their unusual sleeping arrangements at relatives' houses.
The trend was started in 2011 by writer and musician Rhodri Marsden, who invites people to share the unusual places they find themselves sleeping as they visit family for Christmas each year.
One Twitter user from Cambridge shared some snaps of the camper van he is calling home. In an apparent nod to the festive period, the van has been decorated with a string of fairy lights.
Another social media user from London found themselves sleeping in a room decorated with glow-in-the-dark spiders.
.@rhodri This is my girlfriend's childhood room, hasn't changed since she moved out. Not for the arachnophobes (it still glows in the dark!). Oh and it's top to bottom purple. #DuvetKnowItsChrismas pic.twitter.com/q1UFc7qAyA— Bob (@RawkBob) December 25, 2018

She said she was "very grateful to be a part of this very full house".

Many people shared that they would be sleeping on the sofa this year.
Mum's flung the spare duvet at the sofa, but Nan's still watching TV so no chance of sleep yet. Have been given a sheet this year so I don't stick to the leather sofa #luxury #DuvetKnowItsChristmas @rhodri pic.twitter.com/sUIyLlHQou— Mild Peril (@mildperil) December 24, 2018

Bringing family members together under one roof at Christmas can sometimes lead to conflict. Lara found herself "enduring #DuvetKnowItsChristmas" after chasing her owner's in-law's cat.
Others have been sharing examples of the "ancient artefacts" unearthed while rummaging through their childhood bedrooms.

Some took the opportunity to reflect on their changing cultural tastes.
