Imagine that you walk into a room to grab something off the coffee table. You enter the room, only to stop in your tracks-a slight panic sets in as you realize you forgot why you walked in there. Feeling like you are in a haze, you scan the area to see if you can pick up on a visual clue that will lead you to what you need to retrieve. Frustrated, you leave the room again. Knowing that your memory is fleeting makes you feel upset and confused. Why are your thoughts so temporary?
