Visualization is a technique that is typically used in the field of psychology. The person who uses visualization is supposed to create mental images or events in order to solve problems at hand, understand their past, relax, or even imagine a future. With this technique, psychologists help people imagine how they would feel if they were in the situation they are visualizing. Another name for it is mental rehearsal which includes rehearsing future scenarios in your mind so that you are able to plan and prepare for upcoming tasks.
