Hi Robert,
When you see an omen, you must turn inward and find the answer/meaning there. If you believe in, or have ever worked with spirit guides, you can ask for help in understanding the omen. You can ask for the meaning from The Great Spirit, or "God" as you understand it.
As silly as Trish's answer is, there is a part of it that is true, and that is, that should you choose to seek the meaning of the omen, you could end up on a spiritual journey. You may wish to find a teacher to guide your on your path.
Many Blessings,
Elena
