Very interesting poem, and thinking... focus on the word "Ego" which as many such, can be used both as noun" (love the resonance of "know" and "known" as well as "now" in there and "adjective"...which in this context has an irritating feel. The last line invokes musing... upon the ego itself... which it's true, is not the real thing... ("fictitious")... very thought provoking.
