In my experience it was a sign for you to find a way to believe & have faith in things that you aren't able to find a concrete answer to.
If you or someone close to you has recently been going through some changes, having issues, feeling uninspired, etc. this may be the "wake up call" that is needed to continue to believe, keep the faith, etc. even when things aren't going well.
I hope this makes sense & resonates with you.
