Flicker

Time Out says
Take a break from the horrors of 2020 by tracking down an evil spirit in this immersive Halloween show
Able to nimbly fit itself around distancing regulations and the rule of six, the immersive theatre scene in London is not having a terrible autumn by any means. We’re even getting a Halloween show: ‘Flicker’, from Colab Theatre, is an immersive horror for small socially-distanced audiences that takes place in the company’s Colab Tavern venue (the old King William IV pub). Inevitably we don’t know a huge amount about it, but it concerns a haunting in south London, and the efforts of one Reverend Parks to banish it.
