It isn't directly
related to any movie, just a mixture of many classic 'haunted house' movies like 'The Haunting', 'House on the Haunted Hill', 'The Legend of Hell House' and (if you really want to have a fitting name) there are probably also a few similarities with 'The Uninvited' starring Ray Milland.
