I have so many!
In my flat with my friend the fridge and cupboard doors always used to just sit wide open.
I made my bed every day without fail, stood at the bottom, grabbed the end of the duvet where the buttons are and made it from there and 6 days out of 7 when I came back the duvet had rotated 90 degrees so the buttons were on the side but still neat, on occasion my bedside clock would also have been turned around to face the wall.
In my parents house I was once happily chatting away to my mum (sleepily i may add) and she left, asked her in the morning why she had come in to chat at such a random hour and it turns out she hadn't.. but there was definitely someone in my room. My phone in the same house also started playing music at 3am.
In my new house we couldn't find my sons dummy in his travel cot he was sleeping in as we had just moved in, pulled the entire lot out of his cot, blanket, pillow, sheet, flicked them all about and gave up, assumed he had chucked it out so I remade the bed and rolled over, looked back in the cot after a few minutes and it was neatly in the centre of his pillow.
Same thing happened downstairs except my partner had taken his dummy and put it 0n the arm of the sofa, it disappeared and then reappeared a short while later in the centre of his pillow in his cot again.
A different house with a friend and we were in the front room and heard a smash from the kitchen, went to the back of the house to check and a load of dishes had just smashed all over the floor by themselves.
Moral of these stories.. I am the one that is haunted.
