It's time to renew our annual observation of the paranormal— not Halloween, silly, but the Curbed Chicago map of real world hauntings. We're not saying no to candy and costumes, but the seriously invested will always want more of the pagan holiday. For all you big believers and the merely curious too, Chicago ain't a bad place to get your spook on. Chalk it up to all those decades as Sin City, a healthy share of epically fatal disasters, and mobster killings, and you end up with boatloads of disgruntled ghosts. Curbed has cobbled together 23 of the gnarliest sites, made such by murders, suicides, unsettling deaths, freak accidents, and extreme loss of human life. Makes you wonder how many fresh hauntings are in the works for generations to come. The mapped city sites are fairly centralized. You can take a sanctioned tour of some of these paranormal hot spots, or just stroll on by in the middle of the night for some in-window apparitions.
