CHAPTER X

“LIGHT” SLEEPERS

He sleeps well who knows not that he sleeps ill.

PUBLIUS SYRUS (42 B.C.).

Someone may say that such things as stimulation of the mind are simple

causes of wakefulness, and so easily overcome that it is hardly

necessary to consider them; yet, simple as they are, they frequently

make the wakeful one impatient. The more complex causes are really as

easily dealt with as these simple ones, when once we have learned to

control the mind. Take, for instance, the complaining “light sleeper”

who cannot sleep if anybody else makes a noise, or if anything out

of the ordinary occurs. He is in a steady state of apprehension lest

something will happen to disturb his rest; and generally something does

happen. A baby cries, a dog barks, a heavily-laden team lumbers by,

an automobile honks, a locomotive shrieks, or a steamer whistles, and

sleep forsakes him for the night.

He pronounces anathema on the offending cause; he pities himself for

his sensitiveness, at the same time that he almost despises his

fellows who are so “dead and unresponsive that they can sleep through

such a racket” he suffers at the thought that he may get no more sleep,

yet he enjoys the prospect of rehearsing to a sympathizing audience in

the morning the tortures of such a delicate organization as his. This

sort of sleeplessness is made up of so many contributing causes that

it is difficult for any but the most perfectly honest man to decide

what makes him so susceptible to noise. But it is undoubtedly true that

some of these causes are due to fear, to training, and, most of all, to

self-interest.

It is always difficult to make the super-sensitive person realize

that his suffering is due chiefly to self-consideration and a desire

to control others. It is an undue recognition of one’s own claim upon

the very circumstances of life that makes one offer so many surfaces

which may be “hurt.” We may be disturbed in our sleep by the ordinary

pursuits of our fellows because we have an exaggerated idea of the

importance of certain conditions that appeal to us and make for our

comfort. We wish to sleep at a certain time, and we should like to

regulate all our neighbors so that they, too, should suspend all

activities at that same time. We accustom ourselves to quiet; and then

insist that we cannot do without it.

There is a story told of a man working in a foundry who formed a part

of two “shifts” of workmen and betweenwhiles slept for some hours in

the foundry. When released from that strain, he found that he could not

sleep at home because it was so quiet, and it became necessary for the

members of his family to unite in making ringing, pounding noises to

lull him to slumber.

It is a well-known fact that those who live near the cataracts of

the Nile cannot sleep if they get beyond the sound of the pounding.

Soldiers, who are wearied after a hard day’s march or fighting, will

sleep soundly beside twenty-four pounder guns steadily firing; or even

sleep on the march, their legs moving mechanically though their senses

are steeped in sleep.

Country people coming to the city are kept awake by the unusual street

noises, while city-dwellers, accustomed to the roar of elevated or

subway trains, are unable to sleep in the country because of the

intense silence which Nature’s noises often emphasize.

Unreflecting man is a creature of habit: if any change occurs in his

routine, he finds it difficult to adapt himself to it. He seldom comes

to understand that it is chiefly insistence upon his own needs as apart

from the needs or interests of others that makes him require certain

conditions for sleeping. In either case the cause of wakefulness is

easily found; but nobody other than the individual most concerned can

remove it.

If we are living in selfish disharmony with our fellows; if we are

indulging feelings of envy, malice, uncharitableness or hatred towards

those about us, we are not likely to sleep refreshingly. All such

emotions do more harm to the one who feels them than to those against

whom they are directed. They may undermine the health, destroy the

mental poise, and blot out the sense of kinship with mankind. The

Hebrews understood that so well that he who would offer a sacrifice is

reminded that, if he have aught against his brother, he must leave his

gift at the altar and make his peace before he can offer an acceptable

sacrifice to God.

If wakefulness be the result of impatience with our brother, there is

only one cure for it: that is, to replace it with loving patience. It

is the lack of love, or the possession of very narrow love, that causes

us pain in our relations with other people.
