What happens as we fall asleep?
There is no sudden or sharp division between being awake and being asleep. When awake, we can become more and more relaxed and engage in what we call day-dreaming, and at these moments in our brains are functioning in a state that approaches that of obvious drains are functioning in a state that approaches that of obvious drowsiness.
The 100-minute rhythm
Their day-dreaminess can actually come and go rhythmically, every 100 minutes. It is an example of yet another biological rhythm, and is present in us while we are awake as well. This rhythm is known as an ultrafine rhythm.
Generally, we are so involved in our social activities that we are quite unaware of rhythm, but on our own, in a dull and boring situation where we have nothing to do, research has shown that we become more restless and less restless, more restless and less restless about every 100 minutes.
We are also more inclined to nibble any available food about once every 100 minutes, and to drowse slightly and engage in day-dreaming, on and off, according to the same rhythm. We now know that alertness and drowsiness can come and go not only according to the twenty-four-hour circadian rhythm, but according to this 100-minute ultrafine rhythm too.
One of the grandfathers of American psychiatry, Dr Weir Mitchell, famous for treating the nervous disorders of soldiers in the Civil War by a regime of total rest, was very interested in disorders of sleep and in the events of drowsiness.
He described how, while we fall asleep, the control of our ideas escapes us as we drowse, and we begin to live in a world apart. The drowsier we are, the more that world gets separated from the real world around us.
Especially if we are in the dark, we begin to have little dreams in which we see events and people that are not really there. We engage in fantasy conversations with our dream companions, we seem to hear our own voice speaking to them and them replaying to us.
Abruptly, we may make a return to full reality and to alert wakefulness, but it is in the late evening and our normal time for going to sleep, then our grip upon reality becomes more tenuous, our little dream experiences become more vivid, we slip further into sleep and when we do suddenly rouse for a moment, wakened by what Mitchell described as a sensory shock, it may be with a sudden jerk.
The voices and visions and other sensation of falling asleep are termed hypnologic (or leading-to-sleep) hallucinations. They are entirely normal and nothing to be concerned about; usually we forget them completely.
If you think you don’t have them, and are interested to find out, them get someone to wake you up just as you are dropping off to sleep, a or train yourself to do so, and immediately write down what you have just been experiencing.
You will find that you have often been hearing your own voice saying some extraordinary phrase, perhaps with strange works that do not really exist.
The father of modern European psychiatry, Dr Emil Kraepelin of Germany, was very interested in these irrational moments when we briefly lose touch.
He was a great collector of the strange phrases of listed while working in much can be found phrases as strange as: Lord String player and muscle sardines’. Some of the oddest form our own collection are: ‘Or squawns of medication allow me to ungather’, and: ‘Only God and Henry Ford have no umbilical cord.’
Although it’s unusual to remember these phrases, if you ask people at a social gathering if they have ever suddenly woken up thinking that their name had been called aloud, there will be many who will acknowledge this experience; and a few who will describe how they had woken up and seen an angel, or someone else in the room, and then a few moments later had realized that they were now fully awake and that the apparition was no longer there.
Generally the visions and voices of drowsiness are not frightening, but if we are in a general state of anxiety or fever, then the visions and voices can form themselves into frightening, but if we are in a general state of anxiety or fever, then the visions and voices can form themselves into frightening phantoms. They are, though, nothing more than phantoms from our own drowsy minds.
