Have you ever experienced something you can't explain?

Ok I was working as a new Nursing aid last week, on the 2nd floor and a patient of mine told she has a daughter that lives on the 1st. She told me her name and showed me pictures of her, and telling me that her daughter used to be a nurse and stuff like that. So, today I worked the 1st floor and I see her daughter, but only she has a different name. And I told others that work there I saw her mom. And they informed that her mom had died years ago. And she was never a nurse. So I am just really confused and don't know what to think. Could I have some how tapped in to another reality or something? Which I really don't believe in that stuff
But, after that I think anything may be possible.
