This dream is quite vivid and packed with symbolism! Let's break it down:

1. Endless White Hallway: Hallways often represent transitions or paths in life. The endless aspect may suggest feelings of being stuck or uncertain about your direction. The color white can symbolize purity, clarity, or a blank slate, indicating a fresh start or the potential for new opportunities.
2. Golden Doors: Golden doors typically symbolize wealth, success, and new opportunities. The fact that they are on either side of the hallway suggests that you have multiple options or paths available to you, but you may need to explore them further.
3. Ducks in Sunglasses and Bow Ties: Ducks can represent adaptability and resourcefulness. The sunglasses and bow ties add a humorous touch, suggesting that you might be viewing a situation in a light-hearted or unconventional way. It could be a reminder to not take life too seriously.
4. Sipping Tea and Discussing Stock Market Trends: This scenario may reflect your thoughts or anxieties about financial matters or investments. It could indicate a need to pay attention to your financial health or to approach your financial decisions with a more relaxed attitude.
5. Newspaper Covered in Crumbs: Newspapers often symbolize communication, information, or news. Being covered in crumbs may indicate that the information you receive might be messy or incomplete. The duck's statement about needing it for later suggests that this information could be significant in the future.
6. Quacking in Unison: This could represent a collective consciousness or the influence of a group on your thoughts. It may also signify the need for you to pay attention to the voices around you or the opinions of others in your life.

Overall, your dream seems to encourage you to explore new opportunities (the doors), approach life with humor and adaptability (the ducks), and pay attention to financial matters while being open to future information that may arise. It might be beneficial to reflect on what aspects of your life feel uncertain and how you can embrace change with a positive attitude.
