The spookiest night of the year falls on a Monday — which just means more parties all weekend long (and on the big night, for those who can rise for work the next day without being a zombie). We've rounded up the best events to get your freak on. 

Crossroads: A Haunted Masquerade

Long Island City’s Paper Factory Hotel will turn its industrial chic aesthetic into an enchanted, interactive haunted house. Guests choose their own adventure (hence the crossroads theme) while roaming through four different spaces in the basement and courtyard, where music and theater performers will transport you from our dreary realm into one of living art with fire-breathers, drummers and burlesque. Costumes are mandatory if you want to dance with the devil in the pale moonlight to music by DJs David Hohme, Adam Gibbons, Anna Morgan and more. $30, Oct. 28, 9 p.m.-4 a.m., 37-06 36th St., Long Island City, paperfactoryhotel.com

Webster Hell

Only the ghosts with the most should come to the official afterparty of the Village Halloween Parade taking over all four floors of the “twisted mausoleum” that is Webster Hell. After the blood of a virgin christens the evening, live DJs take over for a night of debauchery that’s sure to bring together the city’s most stylish ghouls and boys with a $5,000 costume contest. Higher-tier tickets ($79 or $89) will get you unlimited drinks beginning at 9 p.m. $50, Oct. 31, 8 p.m.-2 a.m., 125 E. 11th St., websterhall.com

World’s End

“Come prepared to survive the apocalypse,” says the description of this immersive theatrical party at a TBA warehouse in Brooklyn. Over the course of a night of performances and dancing — to the tunes of a roster of DJs led by Hong Kong’s underground club king, Lee Burridge — attendees will rebuild society based on equality, community and spirituality. And just in case you have any doubts, the event is co-produced by Bushwick’s queens of themed parties at House of Yes. Oct. 28, 11 p.m.-6 a.m. 21+, costumes mandatory, nightout.com

Inferno

The McKittrick Hotel’s immersive Supercinema parties are anything but cheesy watch-alongs. This is the home of “Sleep No More,” after all. For its salute to old Hollywood on three nights this October, expect all-out decor, pop-up shows, glamorous people and, importantly, an all-night open bar. This year, come dressed as your favorite classic movie monster (i.e. Wolfman, Bride of Frankenstein, etc.) and you’ll fit right into the Golden Age motifs decorating the venue. $85-$200, Oct. 28, 29, 31; 10:15 p.m., 530 W. 27th St., supercinemanyc.com

Stranger Things Party

Netflix’s “Stranger Things” has all the elements of a great party. Join your fellow fans (so, most of the city) at Lot 45 to travel from sleepy Hawkins, Indiana, into the strangest corners of the Upside Down. Expect to dance to all the nostalgic ’80s hits, take Dungeons & Dragons breaks, eat enough waffles to perhaps activate your own latent superpowers and more themed fun. $20-$60, Oct. 23, 10 p.m.-2 a.m., 21+, 411 Troutman St., Brooklyn, eventbrite.com

Brew at the Zoo

Party animals can kick it with some real animals this year when the Bronx Zoo holds its first Brew at the Zoo. Get in after-hours to enjoy more than 100 beers from over 40 craft breweries, plus nosh from Nathan’s Famous, Wafels & Dingels and local restaurants. Head to Astor Court for live music, games and a costume contest, but make some time to wander — exhibits like World of Reptiles and Madagascar! will be open. $44.99. Oct. 29, 7-11 p.m., 2300 Southern Blvd.

Village Halloween Parade

After 43 years, there’s still nothing like getting freaky all over Greenwich Village with the rest of the city. With new spectacles every year and costumes too elaborate to wear anywhere else, the Village Halloween Parade is where the spooks come to show off. The theme is Reverie, but don’t let that stop you if what’s inside your heart is more “Nightmare on Elm Street.” Anyone in costume can walk in the parade. Free, Oct. 31, parade begins at Sixth Avenue and Canal Street, going north on Sixth to 16th Street, halloween-nyc.com
