The meaning of this symbol of evil depends greatly on the details of your dream. If you dreamed of him surrounded by his traditional instruments of punishment, you may want to consider talking to a counselor about any guilty secrets you've been hiding. If your dream involved fighting him off, you will outwit those who are trying to harm you; if he spoke to you, it signifies a great temptation you will find difficult to resist. If your meeting with him was congenial, you may want to consider getting a medical checkup.
