Here's our pick of the most interesting, unusual and amusing ways to mark Halloween which, as it falls on a Wednesday this year, has extended out to almost an entire week of gruesome, ghoulish, grotesque and great events. Vaguely in date order:
Horrific: 13th Hour Horror Festival reels off two weeks of horror films and events at Leicester Square Theatre, including Psycho vs Psycho from Cigarette Burns Cinema on 25 October, Zomedy comedy night (where stand-ups corpse) on 30 October and Rich Sandling's Perfect Movie Halloween special on 31 October.
Sub-aquatic: Lost Souls... Part II is a chance to party with the piranhas at the London Sea Life Centre. This is a Merlin production so expect the cast from the London Dungeons to be imported ready to scare the bejeezus out of you round every watery corner on Friday 26 October from 8.30pm-12.30 at Sea Life Centre, County Hall, Southbank (tickets from £10 if you're quick - call 0871 2829201 to book or £20 on the door).
On ice: It's Shriek Week at Alexandra Palace so get your skates on for a Halloween ice disco (take a severed limb with you for maximum fright effect) on Friday 26 and Wednesday 31 October from 8/8.30-11pm (£8.50 — add in a ghost tour and it's £13).
Underground: Time Out Zombie Horror Camp calls for you to zombify yourself, flail your loose limbs to DJ sets from The Horrors, Robots in Disguise and Guilty Pleasures and make sure you learn all the moves to Thriller if you don't want to be left for dead on the dancefloor. Limp to The Old Vic Tunnels on Thursday 25, Friday 26 and Saturday 27 October (tickets £25).
Thoughtful: The London Ghost Conference is a grand day of talks and talking about London hauntings with top authors and experts and wee bit of spooky storytelling at The Bishopsgate Institute on Saturday 27 October from 10.30am-6pm (tickets £20).
Vertiginous: Up at The O2 offer Climb of the Cursed to brave souls willing to be creeped out at base camp, tricked on the way up the Dome and ponder the view with a gothic map in hand. We found the experience exhilarating and challenging with no eerie additions but if you like a seasonal novelty twist, climb it cursed between 27 October and 4 November (tickets £22).
Family friendly: Night Walks: Boo at Bermondsey Halloween Special presents literary London ghost stories inspired by Charles Dickens with an eerie electro slant! Performed by local storyteller Vanessa Woolf. Live soundtrack by Nigel of Bermondsey with 80s kit - a Moog, ring modulator and test oscillator in Bermondsey Square from 2.30-3.15pm on Saturday 27 October (free but please book).
Political: The Zombie Revolution: immerse yourself in zombie-hood and march to the Southbank to be part of an immersive theatrical experience that will teach you a thing or two about first aid — the undead can be helpful too, you know. This is a fundraiser for St John's Ambulance and protest for zombie rights on Saturday 27 October, time tbc (tickets £25).
Rooftop: The Midnight Apothecary brews cocktails to drive out evil spirits in the Brunel Museum roof garden. Be careful apple bobbing after you've had a few on Saturday 27 October from 5-10pm (free entry, cash bar).
Star-struck: Dress as your favourite dead film star for Die Freche Muse presents a Stars of the Silver Screen party at a secret Hackney location on Saturday 27 October from 10pm-4am (early bird tickets £15, £20 after).

On the night itself:

Psychedelic: Morricone Giallo! will be a triptastic, twisted night at Rich Mix with a mash up of live cinema, visuals and music evoking "knife-edge erotica, naked women found dead in fridges and Alain Delon wrestling with giant eels" on Wednesday 31 October from 7.30pm (tickets £14 adv, £16 on the door).
