A very nice start.
I like the style how you play with the words.
Good work on how you made it to make her daydream without noticing her that she is actually shrinking.
Only drawback: you introduced Jessica too swiftly. You start mentioning her, but the reader doesn't know about their relationship. A little bit more detail about her character would have been nice.
If you have more chapters, just post them. No need to upload them in a document.
Keep on the good work.
