Playing Cards dream meaning is explained below using 3 different sources. Each interpretation is shown with its source.

Interpretation 1 — Dr. Mıchael Lennox

Dreams that contain cards are related to working with patterns and all the permutations that are possible when you understand the underlying structure of how life works. Cards are numbered and suited, and through working with these categories, an almost infinite number of possibilities exists. This is an analogy for how life itself works. In this way, playing cards are like a testing ground for becoming more skillful in playing the game of life.

Interpretation 2 — Gillian Holloway

In interpreting a dream of playing cards, remember that red is of good omen and black is unfortunate. Ace is high and deuce is low.

Hearts indicate good fortune in love; diamonds stand for wealth.

Spades point to hard work without reward; while clubs portend disgrace.

The higher the cards in the red suits, the better is the augury.

The higher the cards in the black suits, the worse is the augury.
