There are several symbolisms of panel that might occur in dreams.
The first is that of a spiritual picture – an icon such as a triptych, which may reflect aspects of our spiritual state. Such a picture has been thought to protect against visitation by the devil.
Psychological / emotional perspective: The second image is that of a control panel. This suggests that we have the ability to make adjustments in our lives, some of which may be only small but are important.
Material aspects: A panel of people such as an interview panel or a panel of judges signifies that we have a situation in our lives where we are being judged or are allowing our fate to be decided by others in authority.
