For some unknown-to-me reason I recently stumbled on the Wikipedia page for David Michell's Number9Dream - and laughed! I laughed because the Wikipedia entry is maybe the exact opposite experience of reading the book. The Wikipedia entry lays out each chapter with a simple-clear-precise-proper summary, on the other hand each chapter in the book is an kind of hallucinatory blend of reality/dream-imagination that left me entertained, but certainly/completely without any ability produce a coherent summary paragraph. Number9Dream is not my favorite David Mitchell novel - but it is strangely fun and certainly unique - certainly don't spoil it by reading the Wikipedia entry first!

I have found several David Mitchell interviews online (all interesting and worth searching if you are interested) - a bit arbitrary but one I enjoyed as a place to start:The Paris Review - David Mitchell, The Art of Fiction No. 204 by Adam Begley.
