Tbh, I read this book about weird stuff like that. Stuff where your keys vanish then show up in the fridge. That door being unlocked for you feels like one of those times. Maybe the universe does tiny favors we don't even notice. Makes you wonder what else we brush off as nothing.
Ever notice how these weird things only happen when you're stressed? Your brain might be playing TRICKS to lighten the load. It's like a mental safety valve we don't even know about.
