I was woken up by a nasty nightmare about 1 o'clock last night. As far as I could reconstruct it afterwards, there'd been a loud noise in the flat below or above, which my dreaming mind had construed as someone in the bedroom, complete with hypnopompic hallucination of someone sitting on the bed and shaking it. I assumed this was because I'd forgotten to lock the front door before going to bed. Add in being literally paralysed with fear when I woke up, courtesy of sleep paralysis, and I couldn't convince my hindbrain that it hadn't really happened and there was nobody in the flat, not even after getting up and checking every room. I couldn't sleep properly for the rest of the night.

It appears that my hindbrain was right. The noise was not one of my neighbours tripping over the mat, and something really did shake the bed:

I would note that I lived in California for several years and only once felt a quake. Move back to the UK, and get one six months later. If I'd known what it was seven hours ago, maybe I wouldn't have woken up every hour on the hour for the rest of the night.
