Why I don't eat sugar before bed

This is a story for a College Creative Writing class I'm taking. We had to write a real or made up memory and this is based off a dream I had 2 days prior. We wrote originally in 1st person but we were told to switch to 3rd person. I did some editing from that version. I would love some constructive criticism. This is my first written story, and I want to know what people think.

Summary: A short horror story, not the best summary but that's what it is.
