Warning: I'm still a newbie when it comes to reviews, so don't expect perfection.
This review is not meant to be offensive and is only written to be supportive.
If you think it's offensive, tell me what I can improve on and I'll try to learn from it.
With that out of the way let's begin.
What I liked: I loved the imagery in this story, the flashback of the narrator that's connected to the spinning top, the personification of the great clock, and the anxious tone of the narrator as he tries to touch the top.
What could be improved: Some Grammar, nothing more.
In the sentence, "In this early hour the bright rays of morning rose far away across the ocean on another continent." There should be a comma after the word "hour".
In the sentence, "Hours seemed to pass before it abruptly slowed, teetered for a moment, fell and rolled to a stop, resting innocently on its side." There should be a comma before the word "and".
In the sentence, "After multiple attempts I gave up, and settled back down into the soft, warm bed sheets, longing for a sleep that would not come." The comma after the word "up" should actually be at the end of the word "attempts".
Overall: It's a brilliant story that intrigues me and makes me wonder who is the narrator and who's spinning the top? I liked how you used the spinning top from inception as the image as this story reminds me of one of my own dreams. This is one of my favorite stories I've come by far to read. I can't wait to read more of your stories as you continue writing.
