Turns out this holiday really lives up to its sinister reputation.

It’s not just ghouls, goblins and ghosts New Yorkers need to fear on All Hallow’s Eve — but reports of real mischief, such as pick-pockets, harassment and assault, surge on Oct. 31, according to a Post analysis of crime reports from the past five Halloweens.

The NYPD logged 1,413 crime reports on the holiday last year, 14 percent more than 1,241 crimes reported on an average day in 2018.

Only 21 days in 2018 saw more crime reports than Halloween, when there were 277 cases of petty theft and 244 harassment reports — the top two reported crimes, followed by assault and “criminal mischief,” which includes crimes such as damaging graves and graffiti.

There were no murders and one rape reported.

Previous Halloweens have seen far more blood spilled.

Fashion writer-turned-rapist Peter Braunstein dressed as a fireman on Halloween 2005 to coax his way into his female co-worker’s Chelsea apartment. Once inside, he held her hostage while molesting her for 13 hours — all to get revenge on an ex-girlfriend.

Braunstein fled to Memphis and was featured on America’s Most Wanted five times before cops caught him in December that year trying to stab himself in the throat.

Exactly 12 years later, on Halloween 2017, alleged terrorist Sayfullo Saipov drove a truck onto a crowded West Side Highway bike path, killing eight. He faces the death penalty in the case.

Federal authorities say Saipov chose the holiday because he knew the crowds would be dense.

Other perps seize the opportunity to hide behind a costume while blending with revelers.

A man wearing the Ghostface mask from the movie “Scream” reportedly fired at a crowd on a Washington Heights sidewalk just after 2 a.m. on Halloween night last year, hitting two victims.

The shooting is among a series of violent events that turned Halloween 2018 into a night of mayhem.

Five others were reportedly shot earlier in the day in four boroughs and three were stabbed — one by a man in a red light-up mask.

Forensic psychologists say the holiday’s mischievous nature inspires criminals.

“Halloween is a celebration of the dark side — a time when we expect and almost accept petty crimes and mischievous acting out,” said forensic psychologist Barbara Kirwin, the defense shrink for serial killer Joel Rifkin. “Mostly it acts as a pressure valve that allows repressed people to release some of their pent-up anger and hostility.”

In Greenwich Village, where millions gather for the city’s annual Halloween parade, the NYPD precinct covering the parade zone received 22 crime reports last Halloween, compared to a daily average of 1.3.

The 45th Annual Greenwich Village Halloween Parade.

Half of the 6th precinct callers reported thefts, five of the alleged crimes happened on the street, two in bars and two in the subway system.

Beyond the Big Apple, Halloween crime has turned other cities into real fright nights.

Oct. 31 is among Boston’s most violent days of the year, according to a study of Halloween crime trends.

“The evening violent crime count on October 31 is about 50 percent higher than on any other date during the year, and twice the daily average,” criminologist James Alan Fox wrote for the Boston Globe, noting criminal activity peaks during trick-or-treat hours, and trails off later in the night.

“The most popular hours for gathering Snickers and Junior Mints around the neighborhood are apparently also the prime time for violent crime.”
