[Total dream loss secondary to left temporo-occipital brain injury].

Recently the case of a woman who reported cessation of dreaming after a bilateral PCA stroke but without REM sleep loss has been reported, suggesting that deep bilateral occipital lobe damage including the right inferior lingual gyrus may represent the "minimal lesion extension" necessary for dream loss. ⋯ Our patient demonstrates that a unilateral left temporo-occipital injury could be sufficient for losing dreams.
