Dream of mother, snake, father

A snake was hiding downstairs in the house. The snake slithered out from its hiding spot and swallowed my father. It slithered around and then ate my mother, and then my sister. I was in my bed relaxing upstairs. I went downstairs for water and I saw what the snake had done. THe snake went after me. I ran outside, running away from it. but it gained on me and bit me, killing me.
