V.--TRANCE AND SLEEPWALKING.

DEAR ARCHY.--The subjects which remain to complete our brief

correspondence, are Religious Delusions, the Possessed, and Witchcraft.

In order that I may set these fully and distinctly before you, it is

necessary that you should know what is meant by Trance.

You have already had partial glimpses of this comprehensive phenomenon.

Arnod Paole was in a trance, in his grave in the church-yard of

Meduegua: Timarchus was in a trance in the cave of Trophonius.

But we must go still further back. To conceive properly the nature of

trance, it is necessary to form clear ideas of the state of the mind in

ordinary sleeping and waking.

During our ordinary waking state, we are conscious of an uninterrupted

flow of thought, which we may observe to be modified by three

influences--the first, suggestions of our experience and reflections,

impulses of our natural and acquired character; the second, present

impressions on our senses; the third, voluntary exertion of the

attention to detain one class of ideas in preference to others.

Further, we habitually perceive things around us, by or through

sensation. But on some, and for the most part trivial occasions, we seem

endowed with another sort of perception, which is either direct, or

dependent on new modes of sensation.

Again, the balance of the mental machinery may be overthrown. The

suggestions of the imagination may become sensorial illusions; the

judgment may be the subject of parallel hallucinations; the feelings may

be perverted; our ideas may lose connexion and coherence; and

intelligence may sink into fatuity.

So much for our waking state.

During sleep, there are no adequate reasons for doubting that the flow

of our ideas continues as uninterrupted as in a waking state. It is

true, that some persons assert that they never dream; and others that

they dream occasionally only. But there is a third class, to which I

myself belong, who continually dream, and who always, on waking,

distinctly discern the fugitive rearguard of their last sleep thoughts.

The simplest view of these diversified instances, is to suppose that all

persons in sleep are always dreaming, and that the spaces seemingly

vacant of dreams, are only gaps in the memory; that all persons asleep

always dream, but that all persons do not always remember their dreams.

The suggestive influences that modify the current of ideas in sleep, are

not so numerous as those in operation in our waking state.

The principal, indeed in general the exclusive, impulse to our dreaming

thoughts, is our past experience and existing character, from and in

obedience to which, imagination moulds our dreams.

Not that sensation is suspended in sleep. On the contrary, it appears to

have its usual acuteness; and impressions made upon our senses--the

feelings produced by an uneasy posture, for instance, or the

introduction of sudden light into the room, or a loud and unusual noise,

or even whisperings in the ear--will give a new and corresponding

direction to the dreaming thoughts. Sensation is only commonly not

called into play in sleep: we shut our eyes; we even close the pupils;

we cover up our ears; court darkness and quiet; knowing that the more we

exclude sensible impressions the better we shall sleep.

But the great difference between sleeping and waking, that which indeed

constitutes the essence of the former state, psychically considered, is

the suspension of the attention--all the leading phenomena of sleep are

directly traceable to this cause: for example--

In sleep we cease to support ourselves, and fall, if we were previously

standing or sitting. That is, we cease to attend to the maintenance of

our equilibrium. We forget the majority of our dreams: attention is the

soul of recollection.

Our dreams are often nonsense, or involve absurdities or ideas which we

know to be false. The check of the attention is absent.

Our ideas whirl with unwonted rapidity in our dreams; the fly-wheel of

the attention has been taken off.

When we are being overcome with sleep, we are conscious of not being

able to fix our attention.

When we would encourage sleep, we endeavour to avoid thoughts which

would arouse the attention.

Though the sensibility of our organs is really undiminished, _it seems

to be lowered_ in sleep, because then no attention is given to common

sensation.

Sleep, however, it should be added, may be either profound, or light, or

imperfect; in the two latter cases, the attention seems to be less

completely suspended.

So, in sleep, it is the attention alone that really sleeps; the rest of

the mental powers and impulses are on the contrary in motion, but free

and unchecked, obtaining their refreshment and renovation from

gambolling about and stretching themselves. The inspector only slumbers;

or, to use a closer figure, he retires to a sufficient distance from

them, not to be disturbed by any common noise they may make; any great

disturbance calls him back directly; likewise, he sits with his watch in

his hand, having a turn for noting the flight of time.

In contrast with the above conception of the states of sleeping and

waking, the alternations of which compose our ordinary being, I have now

to hold up another conception, resembling the first, of which it is the

double,--but vaguer, more shadowy, of larger and gigantic proportions,

from its novelty astonishing, like the mocking spectre of the Hartz;

which is yet but your own shadow cast by the level sunbeams on the

morning mist.

All the phenomena embodied in this conception, I propose to denominate

Trance. But let me premise that all do not belong to every instance of

trance. If I undertook to specify the external appearances of the human

species, I must enunciate among other things, as colours of the skin,

white, yellow, brown, black; as qualities of the hair, that it is

flowing, soft, lanky, harsh, frizzled, woolly; but I should not mean

that every human being presented all these features.

Then, as our ordinary being presents an alternation of sleeping and

waking, so does trance-existence. There is a trance-sleep and a

trance-waking to correspond with ordinary sleep and ordinary waking.

As natural sleep has different degrees of profoundness, so has trance

sleep. They present a latitude so extensive, that it is convenient and

allowable to lay down three different degrees or states of trance-sleep.

Then, of trance-sleep first, and of its three degrees.

The deepest grade of trance-sleep extinguishes all the ordinary signs of

animation. It forms the condition in which many are buried alive. It is

the so-called vampyr state in the vampyr superstition. [See Letter II.

of this series.]

The middle grade presents the appearance of profound unconsciousness;

but a gentle breathing and the circulation are distinguishable. The body

is flexible, relaxed, perfectly impassive to ordinary stimuli. The

pupils of the eyes are not contracted, but yet are fixed. This state is

witnessed occasionally in hysteria, after violent fits of hysteric

excitement.

In the lightest degree of trance-sleep, the person can sustain itself

sitting; the pupils are in the same state as above, or natural; the

apparent unconsciousness profound.

Two features characterise trance-sleep in all its grades. One, an

insensibility to all common stimulants, however violently applied; the

other, an inward flow of ideas, a dream or vision. It is as well to

provide all words with a precise meaning. The term vision had better be

restricted to mean a dream during trance-sleep.

The behaviour of Grando, who had been buried in the vampyr state, when

they were clumsily cutting his head off, makes no exception to the first

of the above positions. He had then just emerged out of his

trance-sleep, either through the lapse of time, or from the admission of

fresh air, or what not.

It will not be doubted that the mind may have visions in all the grades

of trance-sleep, if it can be proved capable of them in the deepest;

therefore, one example will suffice for all three cases.

Henry Engelbrecht, as we learn in a pamphlet published by himself in the

year 1639, after a most ascetic life, during which he had experienced

sensorial illusions, was thrown for a brief period into the deepest form

of trance-sleep, which event he thus describes:--

In the year 1623, exhausted by intense mental excitement of a religious

kind, and by abstinence from food, after hearing a sermon which strongly

affected him, he felt as if he could combat no more, so he gave in and

took to his bed. There he lay a week without tasting any thing but the

bread and wine of the sacrament. On the eighth day, he thought he fell

into the death-struggle; death seemed to invade him from below upwards;

his body became rigid; his hands and feet insensible; his tongue and

lips incapable of motion: gradually his sight failed him, but he still

heard the laments and consultations of those around him. This gradual

demise lasted from mid-day till eleven at night, when he heard the

watchmen; then he lost consciousness of outward impressions. But an

elaborate vision of immense detail began; the theme of which was, that

he was first carried down to hell, and looked into the place of torment;

from thence, quicker than an arrow, was he borne to paradise. In these

abodes of suffering and happiness, he saw and heard and smelt things

unspeakable. These scenes, though long in apprehension, were short in

time, for he came enough to himself by twelve o'clock, again to hear the

watchmen. It took him another twelve hours to come round entirely. His

hearing was first restored; then his sight, feeling, and motion

followed; as soon as he could move his limbs, he rose. He felt himself

stronger than before the trance.

Trance-waking presents a great variety of phases; but it is sufficient

for a general outline of the subject to make or specify but two

grades--half-waking and full-waking.

In trance half-waking, the person rises, moves about with facility, will

converse even, but is almost wholly occupied with a dream, which he may

be said to act, and his perceptions and apprehensions are with

difficulty drawn to any thing out of the circle of that dream.

In trance full-waking, the person is completely alive to all or most of

the things passing around him, and would not be known by a stranger to

be otherwise than ordinarily awake.

I propose to occupy the latter half of this letter with details of cases

exemplifying these two states. Those which I shall select, will be

instances either of somnambulism, double consciousness, or catalepsy,

the popular phenomena of which I take this occasion of displaying. By

these details the following features will be proved to belong to

trance-waking.

1. Common feeling, taste, and smell, are generally suspended in

trance-waking. In trance half-waking, sight is equally suspended. In

trance full-waking, every shade of modified sensibility up to perfect

possession of sensation, presents itself in different cases, and

sometimes in successive periods of the same cases.

2. The general diminution or suspension of sensation is, as it were,

made up for, either by an intense acuteness of partial sensation, often

developed in an unaccustomed organ, or by some new mode of perception.
