for example
dream was also abused by the villagers, he would always call for night but he would never come
When Dream got to weak (since im assuming the skeleton bodies are fragile), the villagers went after night. Dream tried to stop them but never succeeded, then he remembered his suffering. He would sometimes watch from far where night was getting hurt. if the villager does extreme damage, dream would still get mad and get pretty violent-
oh and dream is older than Night-
