I’m well aware that many people have difficulty getting to sleep. But perhaps an actual class on sleep techniques is not the best solution.
Back in college, I had more than a few professors whose classes would have been excellent for an insomniac. Especially the American history prof who repeated every important fact twice for the benefit of those who were still awake and actually taking notes. In art school, the shrill-voiced teacher of pre-Columbian art would enunciate the mostly unpronouncable names associated with the subject as we leaned against our seatmates and lost consciousness. I still cannot bring myself to look at it in museums.
But what worked for me might not do for someone else. Perhaps with a bit of guidance, an insomniac could take a series of classes, true. But tailored to their particular likes and dislikes in course subjects. And via a computer hookup so they could watch lectures in bed in order that their heads won’t do that annoying drop thing when sitting upright. Professors of these classes would naturally be chosen for their dull, quiet voices with emphasis on droning. Lots of diagramming on low-contrast blackboards.
Just thinking about it makes me want to drift off.
