Before the eviction on Sunday at the garden Maria told Angel and peace the dream she had where she was told to get close to Angel that angel will help her solve a problem she had.
Angel couldn't understand but peace told her that it might not necessarily be Angel but may be any other housemate.
Now my understanding of this is that God because of his infinite mercy use to show us things about ourselves in the dream.the person God want her to get close is whitemoney whom she hated for no good reason ,which worked against her and Queen got the grace instead so it is advisable we keep record of our dream and ask God to open our mind for good interpretation

Why will God not send the message directly instead of encrypting it?

That is why it is called dream you need the gift of interpretation to explain it
