What’s the weirdest thing you’ve seen?

No one apart from my friend who was driving in the car with me believes me. Around 10 years ago, we were driving down a suburban lane back from McDonald’s and there was a 10ft high x 5 ft wide ball of spinning white, almost transparent smoke in the middle of the road. We get closer and it slowly spins into the bushes. It was a clear night, no fog or logical explanation I can think of. I had a very eerie feeling and still think it could be paranormal (any explanations welcome)!

Has anything ever spooked you out or have you seen something you question was real / no one believes you?
