Do you dream? If so, what sorts of dreams have you experienced? If not, perhaps reading up on the experiences of others in their dreams may prove beneficial.
Also, are you writing in 1st person or 3rd person, or even switching between views to emphasize the dream sequence? How the events are presented will need to be worded differently depending on the viewpoint.
Last, is the character typically self-introspective? Are they aware that they are dreaming? Should they be aware from the beginning that they are dreaming? Presenting a given scene or sequence as factual to the reader may cause dissonance if later the character views those events as only a dream. Other combinations are possible too, each with a slightly different impact. What do you wish to evoke?
As for myself, I dream extensively, so I have learned over the years some of the logic my particular dream environment operates on. In discussing dreams with others, I have also learned that shared characteristics of dream environments are only occasional, and unique arrangements per person seem to be the norm.
If I may suggest, perhaps a recounting of the bits she sees, more of a visual journey. Perhaps she realizes that she is dreaming, and then is when the next scene takes place. After establishing the dream state, then change it to the vision state.
