Abstract
We encountered three patients who had experienced hypnopompic visual night-time hallucinations. Their clinical manifestations resembled Charles Bonnet's syndrome and the content of their experiences were understood as attempts at wish fulfillment. However, abnormal REM findings were recognized on polysomnogram at the occurrence of visual hallucination in two cases. We speculated that dysfunction of REM sleep mechanism might contribute to the night-time occurrence of such kind of visual hallucination and that their visual experiences might be reflected by dream content.
