Woke up to find all my kitchen cupboards open - no signs of forced entry

I'm still a bit shaken up by this to be honest. It was last night, around 2:30am. I live alone in a flat in Bristol, ground floor but I've got good locks and I always check them before bed. I'm not the type to sleepwalk or anything daft like that.

I woke up needing the loo and as I came downstairs, I heard this sound like something being shifted about in the kitchen. When I got down there, every single cupboard was open - all the wall units, the undersinks, everything. The back door was locked from the inside, front door locked, no signs of forced entry anywhere. Nothing missing that I can see, nothing damaged.

I live in quite an old converted Victorian house and other tenants have mentioned strange things before. One woman on the second floor swears the place is haunted. At the time I thought that was rubbish, but now I'm not so sure. Has anyone experienced something similar? What would cause cupboards to swing open like that?

This is almost certainly subsidence or settling in an old building. Victorian conversions are notorious for it. Floors aren't perfectly level, and if you've got vibrations from traffic outside or even just changes in air pressure, doors and cupboards can swing open. It's boring but logical. Check if your floors are level with a spirit level.

Could also be wind if you've got any open windows or ventilation issues. Air pressure differences between rooms can cause cupboard doors to pop open, especially old wooden ones with dodgy latches. Have you checked whether any windows were left cracked? Old sash windows particularly leak air around the edges.

Rather than jumping to ghosts, I'd actually document this properly. Keep a log - date, time, weather, temperature, which cupboards opened, what position they ended up in. See if there's a pattern. Is it always the same cupboards? Always at the same time? Is there a water pipe or boiler nearby that might vibrate? Could be something genuinely odd, but it could also be explainable once you look at the actual data.

Do the poltergeist test - put a coin or a small object balanced in your cupboards before bed. If they're genuinely opening from internal causes (wind, settling), the object might fall out. If it stays exactly where you put it despite the cupboards being open, that's more difficult to explain. Bit silly but genuinely helps rule out environmental causes.

Have you considered sleep disturbance? Honestly, waking at 2:30am in an unfamiliar state can mess with your perception. Your brain doesn't work normally when you're half-asleep. I'm not saying you're lying, but is it possible you're misremembering the sequence of events? Did you check systematically whether they were already open before you heard the sound?
