There are dreams; then, there are vivid dreams that seem real and often repeat, and could definitely be past life memories. There is no clear distinction between the two, and the choice is very subjective. The trouble with dreams of any kind, however, is that we often begin losing pertinent parts of the dream as soon as we wake, and try to fill the gaps with our own conscious knowledge of current events. Thus, it is the dreams that repeat themselves, which are often indicative of past life memories. In my own personal experience, dreams are mostly symbolic indicators of my present frame of mind and seem to have no relation to past lives. However, my wife has had dreams, which clearly relate to possible past lives and cause her to sit bolt upright in bed with a conscious and detailed memory of the dream. I call these glimpses, because they have no story line, but they evoke emotions that have no relation to whatever is happening in the present life.
