Predestination in interpretation of dreams
(AKJV) And they dreamed a dream both of them, each man his dream in one night, each man according to the interpretation of his dream, the butler and the baker of the king of Egypt, which were bound in the prison.
The dreams they saw was accordingly interpretation of their dreams, what is wonderful, because the dreams were before the interpretation. It seems predestination is at work here.
It may also signify that we should do positive dream interpretations if possible, not to cause an evil.
