THERE have been numerous reports in the literature on the descriptive
similarities between a severe nightmare and an acute psychotic episode
. Nightmares may be a prelude to psychotic decompensation, and it has
been suggested that frequent lifelong nightmares may even be diagnosti
c of an underlying vulnerability to psychosis. In this report, we pres
ent a case study of a 40-year old female experiencing chronic paranoid
schizophrenia, whose two witnessed psychotic relapses in the hospital
were immediately preceded by intense and vivid nightmare attacks. Sig
nificantly, the content of these nocturnal dreams was thematically con
sistent with her waking hallucinations, suggesting a direct continuity
between these experiences. We propose that further systematic study o
f the dreams and nightmares of individuals diagnosed with schizophreni
a may be particularly useful in understanding their phenomenological e
xperience.
