A Rosella

I have seen an angel before! (In my dreams) but it was so real and the angel was talking to me but I wasn't listening and just before I woke up the angel told me to look for a Rosella with a blue head green wings and a red tail. Then the angel told me look next to it (then I woke up) and when I was doing my homework I saw a Rosella preening a sparrow! I don't know what it means but could you tell me!
