Metaphors and the Brain

Have you ever been told by someone that they had a rough day, and then have had some sensation of sandpaper on your fingers? It has been found that the brain may replay sensory experiences to assist in the understanding of metaphors. MRI brain imaging has shown that a specific region of the brain important for sensing textures, through touch, called the parietal operculum, is activated when the patient is given a sentence with an implemented metaphor. Basically, this means that the area of the brain involved with recognizing and memorizing touch is active when the words describing a texture are used. This makes me wonder if having experienced the texture of which the metaphor uses can be detrimental to the understanding of the metaphor itself.
