To dream of an archaeologist represents you or someone else that is trying to bring something from the past back. Finding value in old relationships, habits, or situations. Negatively, it may be a sign that you are viewing old problems like they are good thing.
Example: A man dreamed of an archaeologist talking to him. In waking life he was beginning to have feelings for an old girlfriend that he had had a horrible falling out with. The archaeologist represent his attempt to find value in the failed relationship.
