Often times we are triggered by scents, music, colors, or random sounds of past experiences that are both amazingly unforgettable and at the same time horrendously unforgettable. When presented with such situations it can cause in us great euphoria or lead us down a dark path resembling depression. It can take a few moments of silence to get us back to normal but sometimes it takes a lot longer to move forward with our lives. In these instances we often wonder Who was that? while looking at old pictures with previous lovers or old friends.
