My attempt at Ole Lukøje (Which translates to "Ole Shuteye" or "Ole Eye Closer"), also known as Jon Blund in Norway and Sweden.
He is the Nordic and German version of the Sandman, a creature said to put children to sleep by sprinkling magic sand in their eyes so they have to close them. Ole is a bit different in that he carries an umbrella (sometimes two) which he folds out after putting the children to sleep, and it cause the children to dream.
He sometimes have a darker side to him as well. He is also connected with death, and occasionally he puts someone to sleep forever, meaning he is responsible for people who die in their sleep.
