A fridge creature

When I went to bed I wanted to have a drink but I did not have a bottle with me . When i went downstairs to have a drink the fridge was moving about ,I was to scared to open the fridge door .So i ran up stairs and hid under the pillow.The next day I went to get the milk from the fridge but this time it did not move at all it was a still a wall .When i opened the fridge door there was a big green go gob goblin .Then it screamed at me.
