To dream that you are playing a game of cards represents your ability to strategize in various areas of your life. In particular, diamonds indicate wealth and materialism, clubs indicate work and industry, hearts indicate happiness in love, and spades indicate troubling times and disappointments.
To dream that you are shuffling cards signifies indecision. You need to reevaluate your choices.
In particular, dreaming of the king of heart card symbolises a compassionate male figure in your life. It may also mean that you are that compassionate person.
