Do Catholics Believe in "Signs from the Dead"?

Does a passing blue jay remind you of a deceased loved one? Does a
specific number or color call their loss to your memory? Could they
be speaking to you through these signs? Today, Fr. Mike opens up
about navigating the loss of his own mother and finding hope and
peace in the midst of that grief. The bottom line is, your loved
ones can't cause these "signs" to happen—only God can work in
nature in that way. But these unexpected occurrences can be a
reminder to pray for your loved ones and to recall the gift of
their lives.
