The image of a kangaroo is closely connected to that of a loving family, the image of both maternal and paternal love. The element which makes the kangaroo one of the most important animal symbols for family love and protection is the pouch called a marsupium in which they carry their youngs after birth.
In conclusion, if a kangaroo appears in your dream this may mean that you feel the need to love and protect someone else or you feel the need to receive such love and attention.
If in your dream the kangaroo is aggressive or attacks you this may be interpreted as a forewarning that you will be soon accused of bad deeds you have not done and this is going to jeopardize your reputation. However, if you succeed to kill the kangaroo that attacks you, this is a good sign that you are going to overcome all burdens in the way or win the fight against your enemies by proving your innocence.
