The ace is the first card in the deck, sometimes associated with the number 1, so a dream about an ace from a deck of cards can have to do with something new in your life, such as the start of a new project or the beginning of a new relationship.
Traditionally, the Ace of Spades is a symbol of death.
In a dream, it can represent the ending of something old and the beginning of something new.
The Ace of Hearts can symbolize love or passion, and the Ace of Diamonds can symbolize wealth – material, emotional or spiritual.
The Ace of Clubs can symbolize anger (hitting or being hit with a club). It can also symbolize a need to belong (to be a part of a club).
The ace can be the highest or the lowest card in the deck, so if you dream about an ace it can mean that are uncertain about the outcome of a project, or it can mean that you are unsure of where you stand in a relationship.
If you dream that you are a flying ace, you may be seeking more excitement and adventure in your waking life.
You could also feel that you are the only person who can resolve an argument.
