Haunted houses have been a guilty pleasure of mine since my childhood years in Jersey Shore amusement parks. In fact, I relish the thought of them.

With Halloween fast approaching, ghosts, goblins, ghouls and everyone’s current fave, vampires, are drooling at the chance to frighten normally unflappable New Yorkers.

And they’ll do that at specially created haunted houses around town, all open now. Be advised, these are definitely not for the kiddies. From the zombie strippers at “Blood Manor” to the scantily clad pole-dancing ghouls in “Nightmare: Vampires,” risqué content reigns. And that’s not even talking about the rampant gore on display.

“Nightmare: Vampires” is the sixth annual exhibit created by Timothy Haskell, a modern-day theatrical equivalent to famed cinematic horror gimmick-meister William Castle. This year’s theme is all about the bloodsuckers who are currently so much in vogue.

The experience begins with a tour through MoVA (Museum of Vampire Artifacts), containing displays of ersatz vampire relics and real-life killers.

You then proceed through numerous installations of gruesome vampire-inspired scenes featuring, among other things: random body parts (disembodied hands serve as the resident deejay); some unfortunate sheep; a threatening female succubus; and a “claustrophobia room” in which the walls seem to be closing in on you.

You’ll also encounter menacing figures who lunge at you when you least expect it, making all too clear the necessity for the advance warning not to physically strike any of the performers.

“Nightmare: Vampires” provides plenty of chills, but it pales in comparison to “Blood Manor,” now in its fifth season. The fiendish creators of this attraction have truly pulled out all the stops to scare the bejesus out of their patrons. This elaborate haunted house comes complete with legions of monsters, both human and animatronic, that pop out from every dark nook and cranny; a 3-D enhanced “Boudoir of Endless Sleep”; a walk-through giant beating heart; a butcher room featuring strung-up pig carcasses; and 16 other ultra-grisly environments. This is a place that prides itself on spewing “37 gallons of blood per night.”

Dozens of performers, sporting horrific makeup and prosthetics, make sure your experience will not be a comfortable one. (After two go-arounds, I became concerned for their vocal cords.) It’s easy to understand the appeal of these attractions, especially for the young couples in attendance. They are, after all, the perfect date experience, judging by the hordes of terrified young women and the happy male escorts to whom they were desperately clinging.

“Nightmare: Vampires”: NoHo Event Center, 623 Broadway; 212-352-3101. “Blood Manor”: 542 W. 27th St.; 877-340-3002. Both through Nov. 7.
