I choose to review yours because I love Hermione so I like reading stories centered on her.
I loved the dream thing. I actually wrote a similar story where Bellatrix is in a mental institution and the wizarding world is all in her mind, so it might not be the most original plot, but it's still an enjoyable read all the same.
There were a few SPaG stuff, things that affected the overall enjoyment level of your story. For example, there was a common comma mistake you made over and over again throughout the story. (i.e. "conversation," character said staring blankly blah, blah, blah. There should always be a coma after 'said.')
You also changes the tense accidentally a couple of times and orderly's should have been orderlies. There were a couple of similar mistakes with other words as well.
Even so, I liked how the story revolved around a snow globe and how you saw the importance of it by the end.
Interesting story.
