Also known as a killer whale, an orca is a mammal in the dolphin family. Orcas can communicate from long distances and are known to be very smart and family oriented.
Positive: Dreaming of an orca killing a shark could represent God sending a prophetic warrior to help you in a serious situation. Dreaming of an orca could also symbolize God giving you wisdom and strength.
