Do you guys get surprises in a Lucid dream?

Like a big surprise that knocks your socks off? When you say "Whoa, I wasn't expecting that. Where did that come from?"

For me it's usually something beautiful. My biggest surprise was when I was flying through air sitting in an armchair on my way to the Moon, minding my own business. When suddenly 2 glass orbs about 5 feet in diameter flew by me fast, coming from opposite direction. They were semi translucent, beautiful. This literally knocked the wind out of me and I heard my sleeping body gasp twice from surprise.

Do you have a story to share?
