I have had loads happen to me.
In the town we lived in previously was my husband's double, same height, same build, same hair, face etc.
I used to see the double and would wave and call out but I would be ignored. Then I would try to walk upto them or call my husband and say why are you ignoring me? He would say I am in the pub or wherever but not where I was seeing his double.
I also used to see a double of my MIL even though she lived up North and we lived down South.
When we moved here to our new home, I needed some spare keys cut for the house. I put the keys in my boot in a box and went to town to get them cut. When I got there I couldn't find them in the box. They had completely disappeared. I pulled up the mat in the boot, looked under the spare tyre, around the boot without mat, nothing.
Another time I took DS with me to get some other keys cut. Had them cut and we were walking back to the car. Got to car park and realised I didn't have keys. Must have dropped them. Sent DS back to shop and he asked shop owner, he said no keys dropped there, he had given them back to me. Looked all along the route we had taken, no keys.
Never ever found the first set or second set again.
During Lockdown I was using two debit cards in the house for online shopping etc. I always had these two cards within easy reach. On the windowsill. On my table next to my mouse.
I lost one card from the table. I couldn't find it anywhere. Went through handbag/purse/coats/cardigans. Cleared table, checked books, everything. Couldn't find it. Requested replacement.
Shortly after the one on my window sill disappeared. This time searched whole house, turned it upside down, looking under bed, sofas etc. Everything, DH and DS helped me. I hadn't gone out with this card at all. It had to be in house.
Ordered a replacement and that arrived.
Two weeks later, DH moved sofa to hoover behind it.
Right against the back wall, side by side were both my debit cards! I never sat on the sofa with either card and would never have dropped them and not picked them up. To this day we cannot work out how both got under there, despite us constantly looking under the sofa.
Lately, I came home put my postbox key on the chair instead of in it's basket as we normally do. I don't know why I did this. It took two seconds to drop it in it's basket.
So I went to get the key from the chair a day later to put it back.
It wasn't on the chair. I thought I must have put it back in the basket. Nope.
This time I have turned the house upside down, taken everything out, cleaned out cupboards, washing baskets etc and I cannot find the damn key anywhere. It is going to cost me £100 to get the lock and key replaced. I refuse to pay as I know the key is somewhere. I have done the calling to the Saint to help me find it. It didn't work with cards and hasn't helped with keys or this key. I was talking to my postman asking if he knew the model of the postbox to try and get a replacement key cut. He told me previous owner also lost his key and had to call out locksmith who cut him a new key based on the postbox and that is why there is only one. He was there when locksmith was there.
I sometimes give my son cards to hold for me like our town card for discounts and a Tesco giftcard.
I asked him for the towncard back, he said he didn't have it. I told him to check his pockets, coat, etc nope he doesn't have it.
I ordered a new one and paid for it. Three months later he finds the town card in the pocket of his shorts we had previously searched.
Same with giftcard he swore he had given it back to me. Went through all his clothes/pockets/schoolbag. Nothing.
One day washing his school coat, after checking pockets, it was dry, he put it on. Giftcard in pocket and it had been washed!!!
I just want my postbox key back!!!
All the other keys have never ever been found.
