Page "Finnegans Wake" Paragraph 38

Joyce's claims to be representing the night and dreams have been accepted and questioned with greater and lesser credulity.

Supporters of the claim have pointed to Book IV as providing its strongest evidence, as when the narrator asks “ You mean to see we have been hadding a sound night ’ s sleep ?”, and later concludes that what has gone before has been “ a long, very long, a dark, very dark [...] scarce endurable [...] night .” Tindall refers to Book IV as " a chapter of resurrection and waking up ", and McHugh finds that the chapter contains " particular awareness of events going on offstage, connected with the arrival of dawn and the waking process which terminates the sleeping process of Wake.
