Can you move a roomful of people, emotionally? Do you know how you do it?

I’ve discovered (or been taught) a way of describing things or telling stories that enables me to keep a room full of people hanging on every word. What happens is that I see the story I am telling in my head, and I enter into that story, as if I am feeling it now. All the emotions come rushing in, and I put those emotion out there, and it grabs people, I think, because it is authentic and detailed.

Have you ever experienced anything like this? What kind of situation did it happen in? Do you have any insight into how you did it? Did it feel powerful? Did you feel perfectly comfortable doing this, or were you afraid of your own power—uncertain as to whether you were wielding that power in an ethical way? I.e., not manipulating people.
