I can't give you ideas on what to write-because often the best creative writing emerges from writing about your own personal experiences-to which only you are the most knowledgeable about what experiences you wish to write about. However I can explain what the quotes mean and hopefully get you started thinking of possible ideas to include
1)The first quote is basically articulating that individuals sometimes waits-perhaps for another individual, perhaps for a transformation of themselves, of others, or a combination. It can be interpreted as a part of a literal dialogue, but metaphorically, consider the fact that on almost all journeys-we embark on them with a goal in mind, for example, take the HSC, most people go through these vigorous course to get an ATAR which in turn will assist them to get into their ideal university course. You can also consider reasons for which individuals may wait for others to transform-but never fruition, or the journey to reunite with a long-lost parent or friend-but sometimes reality differs from expectations. The possibility is endless, you can well use waiting as an extended metaphor or motif.
2)Essentially, this will be a slightly cliched interpretation, but consider road as representative of journey, whether it be a physical, spiritual, creative, intellectual, imaginative, inner journey is non-material-you can choose which journey(s) you wish to explore in your creative. It is essentially saying that travelling can reveal new insights and new perspectives, like 'new spectacles in a festival'-also consider the fact that in a festival you meet a lot of people, so it highlights the potential transformations we undergo as a result of the interpersonal connections we make on the journeys we undertake-whether voluntarily or involuntarily.
3)Essentially this quote, like the previous two, can be interpreted in a countless number of ways, but if can be possible to read it as it is only in dreams that one can escape from reality and enjoy the realms of imagination and fantasy which the only bounds is within the human mind. The phrase 'dreaming requires no visas' is essentially referring to the metaphysical-spiritual journeys where you don't need to travel across physical boundaries, but nevertheless, there is potential you might end up being transformed by the journeys you undertake-whether by yourself or with others...
Hopefully this helps-make sure you deconstruct the journey rubric thoroughly to ensure you understand all the possible requirements
