For studies of psychological research into sleep, see the following sources:

"For if I sup not well, large, round, and amply, my sleeping is not worth a forked turnip. All the night long I then but doze and rave, and in my slumbering fits talk idle nonsense, my thoughts being in a dull brown study, and as deep in their dumps as is my belly hollow."

Rabelais, Gargantua and Pantagruel, 3/8
