The wiring of our brains is so complex that dreams, memories, wishes, fears...etc., can be processed to create new combinations and patterns that **seem** like something we should be concerned over. This happens often in dreams, and 'may' reflect actual memories combined with desires and fears,etc.

   ...Sometimes it can be useful to follow up on them in real time.... but be very, very wary of assuming they they arrive in some particular order by some arcane outside process inserting them to warn us or explain too much.

The "will to believe" is a tempting thing.. even beyond standard religious settings.
