A New Jersey family fed up with getting creepy notes about their "young blood" is seeking to demolish the spooky home coveted by a mysterious figure known as "The Watcher."

The anonymous letter-writing weirdo has pestered Derek and Maria Broaddus with eerie messages since they purchased the six-bedroom house for nearly $1.4 million in 2014, according to the family.

“Do you need to fill the house with the young blood I requested?” one letter read, according to a complaint viewed by The Washington Post. “Once I know their names I will call to them and draw them out to me.”

Another asked: "Have they found out what is in the walls yet? In time they will.”

The Broaddus' filed suit against the town of Westfield after its planning board rejected their plan to raze the house and subdivide the land so they could build two houses. They say they can't live in the house because of the letters and their attorney says they're caught in a situation they didn't ask for.

A lawyer for the town told NJ.com she couldn't comment on the lawsuit.

"The Watcher" hasn't been identified, though the person claims to be just one member in a long line of so-called watchers.

“My grandfather watched the house in the 1920s and my father watched in the 1960s. It is now my time,” a letter read. “I have been put in charge of watching and waiting for its second coming.”

Some of the letters have been particularly sinister.

“Who has the bedrooms facing the street?" one read. "I’ll know as soon as you move in. … It will help me to know who is in which bedroom then I can plan better.”
