To dream of quarters symbolizes activation or the start of something. Certain beliefs or life situations are beginning, or being put into motion. You may also be listening to new ideas, or experimenting with something new. Feeling just enough value in something to keep believing it matters. Simply wanting something to work.
To find a quarter in a dream represents insight, power, or freedom gained mentally or emotionally with starting something new, or experimenting with ideas. You or some aspect of your personality may gain from being taking action or trying something new. Discovering a reason to keep trying hard or keep active.
Negatively, a quarter in a dream may reflect issues with trying too hard to keep an area of your life active. Pressuring yourself to try hard when it's not important. Making excuses to keep something active. Vainly finding excuses to keep being mean to someone. Showing off keeping something active.
Example: A woman dreamed of walking along the ocean and finding quarters she would keep picking up. In waking life she was using every excuse she could to pray to God. The quarters in this situation may have reflected her feelings about all the situations she was using as an excuse to pray to keep renewing or "activating" her faith in God.
