And again, in the tale of the “Nonnes Preest:”
“Swevenes (dreams) engendren of repletions,
And oft of fume and of complexions,
When humours ben to habundant in a wight.
Of other humours cou’d I telle also,
That werken many a man in slepe moch wo,” &c.
Ev. I sit reproved, fair lady. Herodotus also says, the Atlantes never dream; which Montaigne refers to their never eating anything which has died of itself. And Burton thus sums up his precepts of prevention:
“Against fearful and troublesome dreams, incubus, and inconveniences wherewith melancholy men are molested, the best remedy is to eat a light supper and of such meats as are easie of digestion, no hare, venison, beef, &c.; not to lie on his back,” &c.
Dryden, to ensure his brilliant visions of poesy, ate raw flesh; and Mrs. Radcliffe, I am told, adopted the same plan. We know that green tea and coffee, if we do sleep, induce dreaming; and Baptista Porta, for procuring quiet rest and pleasing dreams, swallowed horse-tongue after supper.
Indigestion, and that condition which is termed a weak or irritable stomach, constitute a most fruitful source of visions. The immediate or direct influence of repletion, in totally altering the sensations and the disposition in waking moments, is a proof of its power to derange the circulation of the brain and the mental faculties in sleep.
