Another one I have is that I'm back in my childhood home, and the house is empty, and I know that I'm the only person there and my parents are long dead. I look out of a window and the garage light is on, I go down stairs, and the light is now out & the back door is ajar, and I lock it. I don't/daren't venture out. I go back upstairs. The garage light is back on and I go back downstairs and the door is open again and this time can't lock it. The door sticks, or the lock doesn't turn or the key is now missing.
