Morpheus and Me

It’s hot outside and I’m on the move a lot recently, and so my sleep pattern is getting progressively more erratic. The only positive aspect of this revoltin’ development is that I’m dreaming again.

Everybody dreams, all the time. Whether you remember them or not depends on a list of factors, but when I’m sleeping well I tend to sleep relatively peacefully. I awake with no recollection of any nocturnal meanderings, and any fading memories are gone by the time I stagger to the bathroom. I suspect that I’m normally too knackered to waste precious REM time, but that’s hardly a scientific analysis.

I don’t really dream very much, at least, not that I remember. And when I do dream the images are often spectacular in their mundanity. I tend to dream about riding the bus, or doing my laundry. Sometimes if I have a big day ahead of me I dream that I’m experiencing that day, but none of the specific events are ever filled in. Basically, I dream in smalltalk.

Until my sleep pattern falls apart, and then I start to dream with greater vividness. Partly this has to do with falling asleep in the middle of the afternoon: it is a noted phenomenon that falling asleep in the middle of the day when the brain is still relatively active results in stranger, more vivid dreams. If I need to get up early but have only managed to snatch an hour or two’s rest I’ll often go back to bed after the morning’s task is done, and it is the sleep around brunchtime that evokes the most bizarre imagery.

Normally this is quite amusing. Dreams notable for their strangeness are sometimes inspiring, occasionally unsettling, but always worth remembering for one reason or another. If nothing else it gives me the opportunity for a spot of navel-gazing in regards to my own unconscious and its workings: all these images come from my own mind, so what on earth do they mean, and what on earth put them there?

My man Sigmund had a similar line of thought, obviously, and he spent a lot more time on his analysis than I ever will on mine. Most people are familiar with Freud’s assertion that what we remember from our dreams is not necessarily what our unconscious is trying to express (the most famous and oft-quoted examples is “when you dream about flying you’re really dreaming about having sex”). In other words, it is the latent content of the dream that is of most significance. Freud alleged that it is pointless to attempt to construct a coherent narrative from the actual dream itself: you’re missing the point if you concentrate on the pictures rather than what they mean.

Freud’s work attracted much criticism due to his perceived obsession with sexual issues (I say perceived because while it’s certainly a much played out theme in his work, and is certainly a dead-end in many cases, he’s not nearly the sexually-motivated nutcase I believed him to be when I started reading his work). His explanation for the existence of dreams themselves was also labelled simplistic, although it’s easy to aim that barb at the first pioneer in any field.

In any case, modern psychoanalysis has moved back towards exploring the ‘real’ content of the dream as most significant. Freud’s work is by no means forgotten however, and in fact it seems as though one of his main areas of interest has survived.

As well as wanting to know what we were really dreaming about, Freud always wanted to know why. If you’re dreaming about flying, and you’re actually dreaming about sex, what links those two concepts together in your head? What factors in your psyche cause you to express things in a certain way?

A lot of my dreams are relatively easy to interpret. I occasionally dream about a particular person who is no longer in my life, and whose presence I sometimes miss: it’s easy to see what that might mean. I sometimes dream of particular events, past and future, that have had a major effect on me: again I can draw the lines myself.

But what about those occasional blistering nightmares? What about the odd sex dreams that have no apparent link with my own romantic or sexual leanings? What about the dream I had last week, where I was spying on my neighbours through a ridiculous steam-punk telescope, only to discover they had knocked through all the separating walls in the apartment building and were now all living in various kinds of tent? What in the upside-down Sam Hill does that mean?

I haven’t a clue, obviously, but it’s rather fun trying to guess. The chances of hitting on some glittering psychological insight are pretty small, but it’s enough to raise a smile. If your dreams are weird enough, people are always interested, and in my experience relish the chance to interpret someone else’s dreams for them, regardless of their opinion on Freud.

I had a very inspiring professor once, who made a comment on psychoanalysis and its place in modern society that has always stuck with me. She said that the best thing Freud had done for the modern individual was point out to us that “our dreams were important enough to be studied like literature.” It’s a nice sentiment, and one easily applied. If you’re going to think about who you are, and why you feel the way you do, then your dreams are an amusing place to start.

Dreams are an interesting area, because they've been studied a lot and not much has been proved.

I've got a really interesting book that unfortunately I've lent out at the second, which esentially describes (with scientific studies for reference) REM sleep as the storage of memory.

So short term memory, without the aid of REM sleep, does not get stored into long term patterns.

I would hypothesise, then, that dreams during REM sleep are manifestations of correlations - since when we see or hear or smell something, that essentially lights up a series of neurons in a unique pattern, but any one of which may form part of a different (possibly related, possibly not) pattern, then it is possible that the thought/image etc. flagged up by that correlated pattern might appear in your dreams.

So if somebody or something has taken up a lot of thought space, and you've got to know a lot of their nuances (i.e. you've devoted a lot of different parts of a large neural pattern to recognising a wide variety of their/its aspects) then that person or thing is more likely to be flagged up when everyday events cross their neural paths.

Of course, this is (as i'm sure Kyle would be able to point out) almost definitely pseudoscientific wankbollocks.

That certainly sounds plausible! It's a more scientific way of looking at it, but I suspect it still leaves you with the same questions (at least at a general level) than a non physiological exploration: why THESE patterns and not others? If the answers are not immediately obvious, what particular part of your neural network correlates to what you've seen in your dreams, and what is responsible for those correlations in the first place?

I think I'm going to have to do a LOT more research.

Hi Josh,

A popular theory that has been knocking around for a while is the ‘Expectation Fulfilment theory of dreaming’. Basically this says that dreaming is the bodies means of deactivating the autonomic nervous system that gets all pent up with emotion when you have some sort of expectation that doesn’t get fulfilled in real life. Most of these are played out metaphorically (giving rise to about a hundred years of woolly Freudian analysis) but some are much more literal. I think this is why some dreams are really, really banal it can just be your brains way of playing out your expectations of the next day. Also, I think the more wanged out of nightmares are a result of any strong emotional feelings you may have at the time especially if you don’t get a chance to ‘let these out’ during the day or if they kick in just before you go to sleep.

Im not sure if Ive explained this very well but when you think about your dreams in terms of this theory it does make some sense...

If you’re interested you should read ‘dreaming reality’ by Joe Griffin. Its an easy to read but fairly scientific book, although it does gets a bit wanky towards the end.

Big up being asleep!

Dreams are a funny funny ol' thing.

There have been numerous theories thrown around, and as Tom has suggested, nothing has been proved. Memory storage and consolidation of the days experiences is probably the most suggested theory - without REM sleep, our ability to learn new tasks is significantly hindered. There are pointers to suggest this is at least a part truth.

As we get older, our paradoxical/REM sleep time (throughout the night) significantly reduces. This could point to the fact that as we grow older, and understand more about our surroundings and have more similar interactions on a day to day basis, this stage of sleep for consolidation and memory storage becomes less required (although still very important).

Muscle atonia (we get paralysed and men also get erections) suggests our body is allowing the brain to fully take over, also preventing the body from being affected by the high levels of brain activity involved in REM sleep as we act out and think through the days experiences (we wouldn't want to start strangling our bed partner if we were wringing out clothes in our dream).

The high levels of activity (almost akin to wakefulness) in the brain during REM sleep may suggest that the brain is living out/recreating events, thought and emotions that have happened (yet slightly twisted by its inability to fully set out a 'correct' environment for our dreams) or creating seemingly unlinked manifestations of events, thoughts and emotions, experienced that day (e.g. dream interpretations). These unlinked manifestations could possibly be neighbouring neural networks firing, which would mean that dream interpretations may all be a bit rubbish (as our neural networks are not all the same). However, it is plausible that either way, consolidation may be the answer.

One final thing about sleep/dreams. Although REM/paradoxical sleep is suggested as the sleep stage where our dreams occur, have people noticed that when we wake, and go back to sleep relatively quickly, the dreams are always really bizarre yet very clear? Or is this just me? There is obviously a correlation with the brain activity during REM sleep (normal dreaming) and also the early sleep stages (weird dreams as mentioned). But without muscle atonia, etc. is this where sleepwalking comes in to play?
