Personally, I don't believe in Duke Zhou, but I still advocate the principle of thinking during the day and doing it at night. The dream about your docile bird combined with what you said about your unsatisfactory work may show that you don't get along well with your boss or colleagues. You want to improve this relationship, so you dream of a docile bird. This is an idealized statement.
We can also interpret your dream as that two birds were on your balcony a few minutes before you woke up. When you hear the birds, you will have this dream about birds. Dreams usually happen when you just fall asleep and are about to wake up, which can explain your dreams reasonably.
By the way, promotion and salary increase is not a dream, it's called daydreaming ~
