In your dream, the presence of the white banana, white apple, and white book suggests themes of purity, clarity, and knowledge. The color white often symbolizes innocence and new beginnings. The white banana catching your attention may represent a desire for nourishment or fulfillment that is both unique and perhaps unconventional, as bananas are not typically associated with the color white.

The second part of your dream involving the dead old man could signify a confrontation with mortality or issues related to aging and the passage of time. Calling 911 suggests a recognition of an urgent situation, yet your calm demeanor reflects an internal processing of emotions, indicating that you may be grappling with feelings about life and death in a more detached or analytical way. The absence of panic in yourself and others may highlight your ability to remain composed in stressful situations or a subconscious acceptance of life's inevitable cycles.

Overall, these dreams may be prompting you to explore themes of transformation, how you handle crises, and your feelings about the changes in life. It might be beneficial to reflect on your current life circumstances and any significant changes or decisions you are facing, as these dreams could be mirroring those experiences.
