Yeah right, you're just a lazy so-and-so who wants to shave lying down

Is that practicable?
Has anyone ever seen this done?

I think I'd use plastic mirror or heatshrink mirror film. If a
bath-sized glass mirror descended from the ceiling unexpectedly, seven
years' bad luck might not be the most immediate of your worries.
