The first one that I remember happened one night, at home, back when I was still going to elementary school.
I was on the blacktop playing at recess, and then I realized I was dreaming. I was still asleep. I was in control. So I flew. Up and I went, sparing above the playground and higher above the grass. Now I was in the light blue sky like a bird.
I felt so good. No backpack holding me down. No parents. Just me up there. Free.
