Demons are evil spirits. The term demon is derived from the Greek word daimon, which means a “supernatural being” or “spirit.” They are not ghosts since they were never a human being before. Most people would think that demons are originally angels who were expelled from heaven for not listening to God’s commands. Others believe that demons are simply supernatural evil spirits who bring you bad luck and hell. They are said to live in the world of hot coals and flames, and burrows of the tortured souls.

Since demons are spirits, they defy the law of physics and could take the form of the anything they desire.
