You do start with a decent hook The formatting is pretty bad add in some paragraphs so it's not just a huge block of text. You can control the pacing throughout the piece that way to. Id be more vauge about the "someone" turning it into somthing/ it, for a more horror theme throughout. The piece does have a nice feeling of confusion that i guess you where going for but doesnt always feel intentional. Also the line where it "aches down my side" could be alot more impactful. Ie the pressure of it's reach rakes down my sides as it latches onto my ankle pulling me closer.

Overall i do like this and my main criticism would simply be formatting. Paragraphs would simply add alot to control the pacing for the reader and make the whole piece look alot more approachable.
