Digging a well or digging in the earth in your dreams is a prosperous dream and has a good Tabeer for you. It may be interpreted the same way as it is here based on the interpretations given by Islamic scholars such as Ibn-e-Sireen and al-Kirmani. With worldly pleasure and the comforts too you won't want for anything....
Taking good dreams as a blessing from Allah Almighty is always important. The good things you intend for other people are also the result of good deeds. If you have great intentions for your belongings, you will also have good dreams, and their interpretations will be good as well.
