Have you ever watched the movie “Ghostbusters”? There is a spirit called “Slimer” in the movie. It always sleeps on a sofa and acts just like a lump of soft thing. My sister has a long holiday during the Luna new year and she came back to celebrate the Luna new year with family. However, she always lay on the sofa watching Korean dramas and without doing anything during these days. I think she is just like the “Slimer”.
