"Imagine if you were a lousy artist. You are in a class. Suddenly, the teacher orders you to listen to the music, and to sketch whatever comes to your mind. You listen to music, Beethoven late quartet for instance. You are very sensitive to the music. You listen to it. Your mind think of the vivid storm, with lightning and thunder, and a mountain towering above it. You get excited about drawing it. However, you cannot draw it, because you have no talent to draw it. You try to draw lightning, but it looks like stick figures. You switch and you draw the mountains. However, they look like triangles.
If you had a stroke that gave you aphasia, it would be just like that. An idea comes to you. However, you cannot explain it, because your language was broken down; just like you cannot draw because your brain was not trained in it. It was very frustrating, because you remember that you did this very easily. Conversation came very easily to you; however, you cannot implement this, because the language of the brain had been damaged. Imagine if you trained for twenty years to develop the artistic part of your brain. However, the stroke wiped this out."
