Paranormal Home Inspectors

A single mom buys a beautiful semi-detached home, but shortly after purchasing the home, strange things start happening. When the dog and kids start reacting she realizes that something odd is indeed going on in her new home. She doesn't believe in ghosts but she has no other answer for what is happening. Is this a case of adjusting to a new home or are the spirits of some former residents still lingering in this house?
