Whether we remember what our brains get up to during the night or not, we all dream.
Margaret Bowater, president of the Dream Network, says dreaming is an important function that helps our brains process the world around us.
"[Dreaming] is built into us right from the very beginning and it seems to be an alternative way of thinking about our life," says Ms Bowater.
"Most of the day when we're awake we have to solve problems, when we're asleep we have a chance to reprocess some of the stuff that we're having difficulty with using the other side of our brain much more, the artistic and emotional side."
