The child adopted in a dream has a metaphorical meaning and stands for giving up on an old vision of life and world and taking up new ideas, thoughts, setting new goals and ideals etc. Consequently, if you dream that you adopt a child means that an important change has taken place in your life or must take place as soon as possible. The same dream may be a good omen foretelling of an increase in your earnings and gains or being successful in your undertakings.
Adopting or being adopted by someone may also mean that you are on the right way to assume or accept something. On the contrary, if you have a dream in which you put a child for adoption, this stands for the rejection of certain ideas.
But in the waking life we are all aware of the fact that adopting a child means new and more responsibilities, therefore a dream about adopting a child may also be a sign that you are going to take up new and possibly more responsibilities.
If in your dream you crave for adopting a child, this is closely connected to your strong desire to search for and regain the child inside you, the happy and serene moments of childhood, the playfulness and lack of worries of that period in your life.
Obviously, the dream of adopting a child may be very common among people - both men and women - who have problems conceiving their own baby due to infertility or simply among individuals who love kids.
