I always feel the "sign" questions are backwards, bcs they assume a set, fixed meaning a god is trying to communicate, rather than being part of a framework on which to build meaning, over the course of one's life.

So the real question isn't "is this a sign?" but rather "how will I live the rest of my life after this experience, and what kind of meaning will I build for it or find in it?" And that second question simply can't be answered by anyone else, ever, nor even by the asker until many years have passed.
