In dreams, quack doctors can represent someone who claims to have very innovative treatment methods when in actuality they use old-fashioned methods. Doctors typically use this symbol of quack doctors to show how it is inappropriate for them to use such low-cost and ineffective treatments as they would be viewed as ignorant and unethical.
In reality the person receiving their treatment is not very helpful. The dreamer probably feels that they are being duped and should have been more responsible in seeking real certified professional treatments instead of a lower cost alternative.
