Is the entire manga such a fever dream?

So after rewatching the bsd anime for the 100th time I decided to read the chapters 113-129.5.

Whilst I loved the anime adaptation I have experienced more 'WTF IS HAPPENING' moments in the last 26.5 chapters of the manga than the entire anime.

Is that because it just happens to be, that there is a lot of 'WTF' moments in the end or does the entire manga feel like that and the anime somehow missed out on portraying that.
