An 86-year-old woman complains of seeing little people running around her room in the evening

An 86-year-old woman complains of seeing little people running around her room in the evening. This has occurred regularly for the past 4 weeks. She denies any auditory or other sensory hallucinations and is systemically well. She has a background of hypertension with poor vision of counting fingers in the right eye and 6/96 in the left due to bilateral ischaemic central retinal vein occlusions. She is otherwise healthy with good neurological function. She maintains full insight and awareness, and her mental status is unaffected. What is the most likely cause?
