Your mind can control your behavior way after the stimulus has been removed. Just a thought of feeling tired can have your eyes feeling heavy in just a moments notice even after a restful night sleep. A bad smell can stay with you long past the flush. We have a tendency to hold onto thoughts even when there is no logical reason for this to occur. I believe it’s part of a self defense mechanism just in case these actually things or feelings suddenly sneak up on us. Yet if we can’t recover to the real world within a “reasonable” amount of time it’s time to get the help we need but the question is will we know it in time or will we trust another to tell us the truth even if our minds tell us something else.
