To ask if anyone can explain this

[Chamonix1]

Left at 6pm, I turned all the lights off in the house. 100% sure.
Husband gets in at 9pm, all lights in the house on, all of them.
Nobody else has keys, no tripped switches.
Why would this happen? Freaking out over someone having been in my house!

I one came home to find Bruce Springsteen blasting out of the stereo full pelt. All doors and windows locked, DH at work.

No explanation. Sorry.

I think it was a ghost who is keeping an eye out for you. She (it must be a she, no he ghost would care) didnt want anyone walking into the house and tripping over and hurting themselves in the dark, so she turned the lights on for you. Just make sure you say thank you, you want to keep her onside!

:)

I'm convinced it's false memory. I clearly remembered putting my car keys in DHs glove compartment when we went out this morning. They were not there this afternoon when we returned. I couldn't find them anywhere in the house either. Found them in my handbag, so I must've put them there. Nothing spooky. It's simply that when you think you've done a particular thing, you create a memory of having done it, and later on it feels like a real memory. iyswim.

Either you left them all on, your mum turned them all back on, or your DH is winding you up.

A burglar would be unlikely to turn them all on in case it attracted attention. A power surge wouldn't turn them on if you'd turned them off at the wall.

Someone or someWoo turned the switches back on..

Ghost.
Not the DP exaggerated because the lamp was on like my ex would

Ive had my hairdryer switch itself on at 1am ...didn't worry me till 12 hours later. Working at home, lost my internet connection, went to look at router in other room....switched off at the wall. Entire work st home system relies on it so I couldn't have not had it switched on all morning.

And I live alone. Well, apart from whatever flicked those two switches that day....

When you say all the lights. Do you mean every single light in the house? Do you usually turn a light off as you leave a room? If so, then I think it's unlikely (unless house very small) that every single light would be on.

Absolutely can't explain that, sorry. Eeeek.

It'll be a false memory. I've done it a few times. I'm always adamant that I vividly remember doing whatever I thought I had, and then a few days later randomly remember that I actually didn't.

I've done it with packing things, locking the car, turning the oven on...

Are all the lights usually left on at the same time in your house?
I'd check with Dh when he says "all" lights which specific lights? My DH would probably be meaning kitchen and one lamp!

Yes, I asked him. Apparently I left both bedroom lights on, the bathroom, hallway, kitchen, living room, conservatory and the little lamp. So when he said ALL the lights he didn't mean just one or two I could've forgotten.
I'm going to go with my mum turning them all back on, as I turned them off as she was very tired.
I think it's unlikely I put my shoes on , grabbed my bag and coat and locked up with out noticing but it's the only sensible explanation!

something similar happened to me .
went out one morning , came back in the afternoon and all the nets in the front windows(4) were all pulled to the side so most of the window were bare.
no one had been in that house all day, that was over 20 years ago and its still a mystery

I hope your DH isn't the type to exaggerate wildly in order to drive his point home. Some people, having had the "we should turn all the lights off when we're not using them" conversation would see the lamp your DM left on and take it as blatant rule-breaking and accuse the other person of leaving all the lights on.
