Dreams filled with stark contrasts, like the noir setting you described, often represent a struggle between clarity and confusion in your waking life. The white void can symbolize a sense of emptiness or detachment, while the school cafeteria tables suggest a return to a place of social interaction and childhood experiences.

Your parents sitting at the end of the table may indicate feelings of being overlooked or ignored in familial relationships. The muffled speech and laugh track suggest a disconnect between your feelings and how others perceive them, highlighting a desire for acknowledgment that isn't being met.

The orange liquid initially perceived as blood could symbolize something vital or emotional that you feel is being ignored or misinterpreted. The flood of blood at the end signifies overwhelming emotions that you might be struggling to express or process. This could point to feelings of vulnerability or anxiety in your life.

Overall, this dream suggests a need to confront your emotions and communicate more openly with those around you, particularly your family. Reflecting on these feelings and seeking ways to express them could be beneficial. Consider journaling or discussing your thoughts with someone you trust to help process these intense emotions.
