About the owl, I don't know what that could mean. Personally, I don't think anything from the environment or from God would tell someone how to get rich quick. The Bible does happen to say "It's easier for a camel to pass through the eye of a needle than a rich man to get into heaven." So if anything, the sign would be for you to look out for the more important things in life, like wisdom from the owl or slowing down so you don't crash into a cute little puppy (could symbolize stepping on people because you want to "win the race" or get rich quick). And maybe the girl coming back into your life is a sign to forgive and forget or past problems will come back to haunt you, just like the girl did.
It's all a matter of perspective and opinion. If you're not sure of the answer, you shouldn't be looking. Anything straight from God or whatever you want to call it (your existence or environment) will be known as soon as you see it. Like the owl making you feel blessed right away. If it made you feel good, chances are it was a good sign, but if you're unsure, don't press it. If it's meant to be known, it will be known
