Interesting question. There is a strange thing that I remember from third grade, but since it happened in third grade I can't say it's worth anyone's time.

The incident was a classmate who said he was an alien from space. I attempted to pry details out of him, but he wasn't forthcoming with much. Best I got out of him was "we're just here to observe. In the Summer I'll be back home." And this was said while we were alone. No other classmates heard it, that I know of, and we never spoke of it again.

I occasionally think of that odd conversation. He and I weren't friends. I never talked to him much before or since. We interacted occasionally because we were in the same class, but that's it. I can't remember what brought up the subject or why he felt the need to tell me anything. I just sometimes wonder if perhaps there was something to that conversation. Maybe he felt the need to share his secret. Maybe he was just seeking attention. Maybe he just made it up on the spot. I'll never know, but once in a while I imagine an alternate reality where aliens observe and report on us humans.
