Dreaming, so crashes into gorge (10)
I believe the answer is:
gormandise
'gorge' is the definition.
(I've seen this before)
'dreaming so crashes' is the wordplay.
'crashes' indicates anagramming the letters.
'dreaming'+'so'='dreamingso'
'dreamingso' anagrammed gives 'GORMANDISE'.
'into' acts as a link.
(Other definitions for gormandise that I've seen before include "gorge" , "scoff like a 28 [PIG] ?" .)
