Brief spinning sensation when turning over in bed

Vignette

A 56-year-old woman reports brief episodes of spinning lasting about 20 seconds, triggered by turning over in bed and by looking up at a high shelf. Between episodes she is well. Examination is unremarkable. Dix-Hallpike test on the right reproduces an upbeating-torsional nystagmus that fatigues with repetition. Bucket SVV is +0.5° with a normal SD. Audiogram is normal.
