To dream of seeing someone disfigured represents a permanent loss you feel in some area of your life. Your perception of long term emotional or physical scarring. A past trauma or relationship still effects you or makes you feel like you have to live with a problem forever. You may feel that you can’t be yourself anymore.
Example: A man dreamed of seeing a horribly disfigured man. In waking life he contracted an embarrassing disease in his youth that prevented him from ever enjoying himself socially.
