I haven't written enough fiction yet for this even to be a possibility.
In my nonfiction writing I have occasionally cited my prior works; but it is more common for me to paraphrase or summarize what I had written earlier.
FWIW, I have been trying to catch up on the earlier fanfic. I had started out planning to read all the Kerth winning and nominated stories, but I have been sidetracked into reading all the works of some authors whose works I especially enjoy. I have noticed that some (I won't name names) have used plotlines and/or descriptive phrases repeatedly. It becomes a lot more obvious when one reads an author's works back-to-back. So to judge by the fanfic I have read, you are not alone.
Joy,
