People with no contact with the koala bear are more likely to dream of this animal. Its because they desire to see a koala up close and thus dream of it as a desire that wants to be fulfilled. The koala is associated with Australia and when you dream of this icon, you are dreaming of that country.
Alternatively, do you have a koala bear soft toy? Do you think your dream had any relation to your toy? If it had, maybe you were dreaming of the person behind the koala. Was it a gift to you from someone? Maybe you might like to check on that person, if they are not staying in your home.
Do you have a different personal interpretation of dreaming of a koala bear? Please share.
