Disgrace is an event or sense of being ashamed of oneself. In dreams a feeling of disgrace could signify issues with reputation, guilt, asking and seeking forgiveness and a need/desire for atonement.
To feel disgrace in a dream often reflects a situation in which we have fallen from a high position and never thought we would get into.
In dreams, many things that have impacted us shame us and make us feel guilty. Disgrace is a term that really stands for being hurt or shamed by events. Guilt comes from feeling like you did something wrong even though you may not have deliberately done it. The people who are guilty are those who feel the consequences of their actions tremendously bad and they want to owe someone something to attain redemption.
