This animation represents the feeling of experiencing Sleep Paralysis: basically is seems as thought your mind is awake while your bodyis asleep and paralyzed. A lot of the time people hallucinate.
Here I animated this still from The Shining and inserted the painting The Nightmare by Henry Fuseli.
This painting has been said to represent sleep paralysis, as a lot of the time it feels as though a demon is sitting on your chest. In this animation the person experiencing sleep paralysis hallucinates the demon jumping out of the painting and onto his chest.
