Detailed dreams: Last night I dreamed that my dad was ill and needed 520 yuan for treatment. I went to the hospital to sell a thin, long cartilage on my shoulder after I had no money. The doctor took it out for me, and I felt pain in gritting my teeth. After taking it out, the doctor said that I would be able to give me money in a week and also check if my organs were working. I was in a bad mood, so I discussed with the doctor. Then I woke up. What does this dream mean?
