This also mean work overload, and to long in a very stressful work situation. To long, with loud people who are always talking loudly, all the time, constantly with no let up. This means you have an excellent memory that is almost photographic. You mind records sounds and images well. You probably remember music as well. It might be best to change jobs and be with quieter people, in a more quiet work place. Your mind is just replaying noise that your mind recorded during a horrible loud work day, with loud constant talkers.
