Account of giving presentations for possible thriller ideas

we were set to prepare a presentation on what we thought would be a good thriller idea. my idea was based on a ghost who lives in this old house. the house was bought by a family which involved a mother and a little daughter. the mother started to rearrange the furniture the furniture but the olg ghost didnt like this so he moved the furniture back and later he killed the mother because he didnt like the changes and then the little daughter couldnt stay alive and then the little daughter died.
