I saw a full moon that slowly became a blood moon and suddenly under its light many people appeared, who were sitting in a rectangular formation, unable to move.
Seeing a full moon in a dream generally symbolizes completeness, transformation, and hidden emotions. When the full moon slowly turns into a blood moon, it can represent a sense of foreboding or danger. The people who appear in the dream, unable to move, may suggest that they are either trapped or powerless in some situation. The rectangular formation of these people could indicate that they are being controlled or oppressed by a larger force.
Overall, this dream could be interpreted as a warning of potential danger or a sense of being trapped. It may also suggest that there is a need to address any lingering emotions or unresolved issues to avoid feeling powerless in waking life.
