The metaphor of hiking in the mountains going up and down hills and valleys is the most appropriate choice because it conveys the cyclical nature of the sleep stages, with periods of deep sleep followed by lighter sleep and then REM sleep, much like the journey of a hiker over varied terrain. The other choices do not accurately represent the cyclical nature of sleep cycles.
