What’s the strangest dream you’ve had?

I was in the garden of a place where I used to live, out in the country. I saw a spere, apparently made of wire mesh, about a metre across, hovering over the lawn, rotating very slowly on its vertical axis. It did this for a few seconds, before darting diagonally over to a higher position and hovering again over the other side of the lawn. It performed these kinds of manoevres several times; hovering, rotating slowly, changing position, before suddenly shooting off into the sky right out of sight.

I had this dream about 25 years ago and it's stuck in my mind ever since.
