Neighbours with numerous and unnecessarily bright motion-sensor floodlights in their gardens.
I was calling the cat in earlier, and it was like a scene from a prison movie as she cut across the lawn - it triggered three (previously uninstalled) lights that, I imagine, could have easily burnt through my retinas if I had stared at them for more than a second.
Might need a welders mask for any further night forays into that coronal discharge.
Part Two (The Saga Continues):
Said feline was, again, beckoned homeward with the traditional: ‘Pspspspspsps!’ noise, and to my astonishment, she managed to trigger them all (including a new one, on their shed) by merely being in the detection zone of one of the things - they must be synchronised!
Mr Neighbour must have been very busy doing that, today…he’s even put outdoor fairy lights around the whole upper perimeter of the garden, to create a welcoming, lulling effect before the collapsing stars activate. Will machine gun nests be next, I wonder?
Any brighter, and I fully expect the lights to disrupt the Space/Time Continuum and create a temporal vortex where the searing beams meet.
Might need more than a welders mask to brave it again, at this rate; possibly require a biohazard suit and a Geiger counter.
More updates will follow, like it or not.
