TRIVIA: Test your knowledge of “all things spooky and scary” while in disguise (so people don’t know how much you study creepy things). Dinner provided by We, The Pizza. Sixth & I (600 I Street NW) 7 p.m. $20

HOME BUYING: Redfin agents will share the ins and outs of buying a home over a few beers during “Home Brew-Home Buying Class and Brewery Tour.” Atlas Brew Works (2052 West Virginia Avenue NE, #102) 6-8 p.m. Free

YOGA: If you want a little personalized instruction before joining a yoga studio, register for this four-part “Yoga for Beginners” class. There are only spots for four people (two are left). Samsara House 2023 (36 R Street NW) 7-8:15 p.m. $75, which includes a spot in all four classes.

SING-ALONG: Sing-along with your favorite “creepy, scary, and ghoulish” tunes, including “Enter Sandman,” “This is Halloween,” “Ghostbusters,” Somebody’s Watching Me,” and more. Don’t worry if your singing voice is also scary. During A People’s Choir you get to sing aloud from anywhere in the bar, so your voice should blend in with the others! Costumes encouraged.
