Here's a couple examples of what I experience. I apologize that one is a little gory. This morning I walked past my kid's room and they had a pencil in their hand and were jumping on the bed. I literally saw her falling and getting stabbed in the face. I saw her falling down many different ways, and scrapes and blood. And in real life I ran in and stopped her and everything is fine. But those images are like memories to me that I can still see. As a less gory example, I do computational geometry and I'm visualizing all of the time. I'm rotating objects around and fitting them into and next to each other in my mind. I'm slicing them, scaling them, projecting them. And yes, I can later draw a picture of or write a textual description of what I imagined. Edit: Again, I'm not saying that you've missed out on anything in your life. The point is just that this is something people really do experience.
