Whenever I have a dream where something is flashing, which doesn't happen very often, I know it means to make a special note of it for future reference. And I can't think of a single time when the flashing message didn't mean something of special importance.
That's so cool!! That's exactly how spirit works. They're like whispers, and very easy to overlook or ignore, but there's something inside that tells you it was a sign. I think she was just saying "hi". I feel like she was conditioning you to be able to recognize her presence in ways other than meditation because you will need this in the future. She doesn't want you to become dependent on meditation in order to communicate.
