This dream is rich with vivid imagery and imaginative symbolism. Riding a bicycle made of licorice down a rainbow road suggests a journey filled with creativity and sweetness, perhaps reflecting a desire for joy and freedom in your waking life. The fact that the road is suspended in space indicates a sense of adventure and exploration beyond the ordinary, suggesting you might be seeking new experiences or perspectives.

The planets and comets made of cotton candy can symbolize the fun and whimsical aspects of life. It may imply that you are in a phase where you appreciate the lighter side of life or wish to escape from everyday stresses.

The toll booth and the talking turtle introduce an element of negotiation or exchange. The request for "three smiles and a secret" may symbolize the need for joy and authenticity in your interactions. This could suggest that you are being called to share your happiness or to connect with others on a deeper level.

Waking up before you could pay the toll might indicate a feeling of being unprepared for a change or transition in your life. It could also suggest that there are emotional or personal exchanges you have yet to address.

Overall, this dream appears to encourage you to embrace the playful and imaginative aspects of life while also being mindful of the connections you make with others. Consider what "smiles" and "secrets" mean to you, and how you can incorporate more joy and authenticity into your daily experiences.
