When seeing something traumatic on TV, or in real life. And especially when reflecting on another's predicament.
Directly following the moment of insight, or reality overload (for want of a better term) I experience a strange sensation on the right side of my brain which can be only described as a brief sensation of bubbly fluid, or bubbles popping?

Hard to describe. I'd be interested if anyone here has the same experience.
Never met anyone who has, yet...
