It is sometimes thought that these early fears of animals are inherited from remote ancestors to whom many wild animals were really dangerous. But I do not think that this has been proven. The variety of these childish recoilings, and the fact that they seem to be just as often from small harmless creatures as from big and mighty ones, suggest that other causes are at work here. We may indeed suppose that a child's nervous system has been so put together and poised that it very readily responds to the impression of strange animal forms by a tremor. Special aspects of the unfamiliar animal, aided by special characteristics of its sounds, probably determine the directions of this tremor.
In many cases, I think, the mere bigness of an animal, aided by the uncanny look which often comes from an apparent distortion of the familiar human face, may account for some of these early fears. In other cases we can see that it is the suggestion of attack which alarms. This applies pretty certainly to the butting ram, and may apply to pigeons and other birds whose pecking movements readily appear to a child's mind a kind of attack. And this supplies an explanation of the fear of one boy of two years three months at the sight of pigs when sucking; for, as the child let out afterwards, he thought they were biting their mother. The unexpectedness of the animal's movements too, especially when, as in the case of birds, mice, spiders, they are rapid, might excite uneasiness. In other cases it is something uncanny in the movement which excites fear, as when one child was frightened at seeing a cat's tail move when the animal was asleep. The apparent fear of worms and caterpillars in some children may be explained in this way, though associations of disagreeable touch probably assist here. In the case of many of the smaller animals, e.g., small birds, mice, and even insects when they come too near, the fear may not improbably have its source in a vague apprehension of invasion.
These shrinkings from animals are among the most capricious-looking of all childish fears. Many robust children with hardy nerves know little or nothing of them. Here, too, as in the case of new things generally, the painfulness of fear is opposed and may be overcome by the pleasure of watching and by the deeper pleasure of "making friends". Quite tiny children, on first seeing ducks and other animals, so far from being alarmed, will run after the pretty creatures to make pets of them. Nothing perhaps is prettier in child-life than the pose and look of one of these defenceless youngsters when he is making a brave effort to get the better of his fear at the approach of a strange big dog and to proffer friendship to the shaggy monster. The perfect love which lies at the bottom of children's hearts towards their animal kinsfolk soon casts out fear. And when once the reconciliation has been effected it will take a good deal of harsh experience to make the child ever again entertain the thought of danger.
The Night Attack.
Fear of the dark, and especially of being alone in the dark, which includes not only the nocturnal dread of the dark bedroom, but that of closets, caves, woods, and other gloomy places, is no doubt very common among children. It does not show itself in the early months. A baby of three or four months if accustomed to a light may no doubt be upset at being deprived of it; but this is some way from a dread of the dark. This presupposes a certain development of the mind, and more particularly what we call imagination. It is said by Dr. Stanley Hall to attain its greatest strength about the age of five to seven, when images of things are known to be vivid.
So far as we can understand it the fear of the dark is rarely of the darkness as such. The blackness present to the eye in a dark room does no doubt encompass us and seem to close in upon and threaten to stifle us. We know, too, that children sometimes show fear of mists, and that many are haunted by the idea of the stifling grave. Hence, it is not improbable that children seized by the common terror and dizziness on suddenly waking may feel the darkness as something oppressive. This is borne out by the fact that a little boy on surmounting his dread told his father that he used to think the dark "a great large live thing the colour of black". A child can easily make a substantial thing out of the dark, as he can out of a shadow.
Yet in most, if not all, cases imagination is active here. The darkness itself offers points for the play of imagination. Owing to the activity of the retina, which goes on even when no light excites it, brighter spots are apt to stand out from the black background, to take form and to move; and all this supplies food to a child's fancy. I suspect that the alarming eyes of people and animals which children are apt to see in the dark receive their explanation in this way. Of course these sources of uneasiness grow more pronounced when a child is out of health and his nervous tone falls low. Even older people who have this fear describe the experience as seeing shadowy flitting forms, and this suggests that the activity of that wonderful little structure the retina is at the bottom of it. The same thing seems to be borne out by the common dread in the dark of black forms, e.g., a black coach with headless coachman dressed in black. A girl of nineteen remembers that when a child she seemed on going to bed to see little black figures jumping about between the ceiling and the bed.
The more familiar forms of a dread of the dark are sustained by images of threatening creatures which lie hidden in the blackness or half betray their presence in the way just indicated. These images are in many cases the revival of those acquired from the experiences of the day, and from storyland. The fears of the day live on undisturbed in the dark hours of night. The dog that has frightened a child will, when he goes to bed, be projected into the surrounding blackness. Any shock in the waking hours may in this way give rise to a more or less permanent fear of being alone in a dark place. In not a few instances the alarming images are the product of fairy-stories, or of ghost and other alarming stories told by nurses and others thoughtlessly. In this way the dark room becomes for a timid child haunted by a "bogie" or other horror. Alarming animals, generally black, as that significant expression bête noire shows, are frequently the dread of these solitary hours in the dark room. Lions and wolves, monsters not describable except by saying that they have claws, which they can stretch out, these seem to fill the blackness for some children. The vague horrors of big black shapeless things are by no means the lightest to bear.
In addition to this overflow of the day's fears into the unlit hours, sleep and the transitional states between sleeping and waking also furnish much alarming material. Probably the worst moment of this trouble of the night is when the child wakes suddenly from a sleep or half-sleep with some powerful dream-image still holding him in its clutches, and when the awful struggle to wake and to be at home with the surroundings issues in the cry, "Where am I?" It is in these moments of absolute hopeless confusion that the impenetrable blackness, refusing to divulge its secret, grows insufferable. The dream-images, but slightly slackening their hold, people the blackness with nameless terrors. The little sufferer has to lie and battle with these as best he may, perhaps till the slow-moving day brings reassuring light and the familiar look of things.
How terrible beyond all description, all measurement with other things, these nightmare fears may be in the case of nervous children, the reminiscences of Charles Lamb and others have told us. It is not too much, I think, to say that to many a child this dread of the black night has been the worst of his sufferings. At no time is he really so brave as when he lies still in a cold damp terror and trusts to the coming of the morning light.
