R2-D2

This dream I had 2 years ago.

I was eating lunch in my highschool courtyard when a large space ship that looked like R2-D2 dropped out of the sky. People started getting out and some of them told me they had just come from the moon, and that it was a cool place to visit. So I of course wanted to go, but then the principal came out and told the people the kids had to go back to class and lunch was over.
