For the last couple of weeks I've been noticing lights on when I come in when I'm 100% sure I've turned them off. Milk out on the side when I'm sure it's been put away. Stuff moved around but not in an obvious way, just a "huh, I could have sworn I left that somewhere else."
Put it down to rushed mornings and my cats playing with stuff.
Been out most of the day, just went into the upstairs bathroom for the first time since this morning and there's blood on the loo tank. Thought it could have come from a cat bringing something in but the door has been closed all day, and it's on the third floor so it's not like they could have got in and out like that. Windows have been closed too.
I have already bought carbon monoxide detectors in addition to the wired in ones. They're all over the house but haven't picked anything up.
Have a loft but the hatch is tiny and doesn't seem to have been disturbed.
Have an internal camera which shows the front door and hall - no activity though it did show my dog going bonkers barking at something outside a couple of times today (though the external camera isn't up yet so I couldn't see what)
Only direct family have keys and they wouldn't do stuff like this. Will be changing the locks tomorrow!
I'm properly creeped out ATM! Husband will be back shortly from work thank god! I'm in the bedroom with the door wedged shut for the moment!
Please someone give me a rational explanation!
