Imagine looking out your window and seeing this staring at your home:

It's a mannequin, wearing a Halloween mask, covered in fake blood, waiting next to a phone with "311" written on it in red paint.

"It's scary. I'm scared to come home. I try not to come home alone, I try not to come home alone with my child. I'm fearful," said one of the Kew Gardens Hills homeowner, who asked we conceal her identity for this story.

She says the gruesome mannequin is the final straw in a dispute that has gone on for almost a year.

It began when their neighbor, Shlomo Klopfer, first hung a single sign reading "dead end" on his fence, facing their home:

"So I asked him about it. I said my daughter can read and she doesn't need seeing dead end," said her husband, who also asked we conceal his identity.

"Which he got very aggressive at and said, 'F you. Not only will I not take it down, I'll add more signs,'" she said.

A promise that Klopfer made good on. We counted nearly two dozen signs hanging on his fence:

"I love the signs. I love this and I'll build another," said Klopfer.

Klopfer says his neighbor has called 311 on him 3,000 times, which she disputes. According to the Department of Buildings website, there are 28 complaints listed for his address dating back to 1997, all while he was living there. Half of the complaints were placed prior to 2010, when the neighbors moved in.

"You see the phone there? 311? She can call from this phone," said Klopfer.

Klopfer's neighbors believe the so-called decorations are part of an intimidation tactic. Kew Gardens Hills is home to one of the largest Orthodox Jewish communities in New York City; the neighbors are Jewish and Christian, respectively.

"I was disheartened to hear that a big part of his hatred was due to our interfaith marriage," said one of the homeowners.

Klopfer denies that their religion has anything to do with his decorations.

"No, no, no. I love people. I'm chaplain. I visit Christians, Muslims, whatever," said Klopfer.

An NYPD spokeswoman confirms officers from the local precinct have attempted to act as mediators, working with local religious leaders in the hope of bringing the feud to an end.

"He was unwilling to sit down with us," said the homeowners.

Because the signs and mannequin are on his property, it's not illegal, according to the NYPD.  The NYPD confirms the neighbor has filed two complaints against Klopfer for harassment.

But Klopfer told NY1 repeatedly that he has no plans to stop adding to his decorations. When we asked if he was concerned what this is doing the to the local property values, he said:

"Why she want to sell?" said Klopfer. "Ask her! ... We got buyers."

But his neighbors are not budging. The home has been in their family for three generations, and while they dreamed of raising their daughter in the neighborhood they grew up in:

"I'm scared for the safety of my child and my family because I don't know how far he will go," said the homeowner.

They say that dream has quickly turned into a nightmare.
