This study is to present a psychopathological analysis of complex hall
ucinatory symptoms - without consciousness breaking up in confusional
state - occuring in patients with acute Guillain-Barre's syndrome diag
nosis requiring neurological intensive care. Finally the patients expe
rience an unitary and closed situation <<close to dream without being
dream>>. This experience is corresponding to the semeiology of the <<o
neiroid experience>> (Mayer-Gross, 1924). The <<oneiroid experience>>
appears to be of syndromic nature independant of any etiological and/o
r nosological classification. But its conceptualization does probably
need widening : the oneiroid world appears to be a creation of a primi
tive function which inserts us in the world before any science or veri
fication.
