I just heard this mentioned on a podcast, but then couldn't remember which one, and can't remember the title either! But I think it was a 3-4 word title with relatively simple, common, monosyllabic words.
It begins with a man waking up from a dream, then going to a house (possibly a party is there), and meets several people he recognizes from the dream, which he finds surprising and inexplicable. I'm not sure what else happens, but I believe it ends with his waking up from the novel's events, which were his dream, but which are now apparently going to be repeated in an endless cycle of dreams-within-dreams.
