Hi there! I am trying to find a movie but I have no idea what it's called or who is in it. I know that it is a scary movie, probably from the 70's or early 80's. I know there were three children, two boys and a girl I think. They were alone in this big house, and they were running up the stairs screaming. They jumped on this bed, and it started to move. When they jumped off, hands began to reach from underneath the bed trying to grab them. Next thing I remember, was they were standing on a porch, or in the doorway looking outside into the night. Their mother was standing there, holding out her arms and telling the children to come to her. The oldest kid, a boy I think, said that's not our mother. Then, her head exploded. That's all I remember. I know the movie left a long lasting effect on me. I really need to find out what it is. Can someone please help me? The Wench
