Once.

Not so much unpleasant as shocking, surprising maybe.

I was in a car with a dog. We were passing through some road work and traffic was moving slow. She barked at the road crew or some piece of machinery and I got this really intense flash of color in my head. Brilliant white at the center, radiating fields of blue, and a fringe of purple with rays coming from it. It was pretty weird.
