Surprisingly enough, I do not completely reject the notion of dream interpretation, though to paraphrase Sheldon Cooper, astrology is complete hokum.
The reason why I consider dream interpretation slightly more realistic is because rather than narcissistically claiming self-importance or self-worth based on arbitrarily defined constellations, dreams are a product of one’s self. Don’t get me wrong, the entire “industry” for dream interpretation is basically a scam to lure in the weak minded, but at its core, a dream is a series of information that your brain is processing during REM sleep. Often, it can manifest in mundane ways, but sometimes the dream is abstract (my favourite) and is thus more confusing. The crux of the matter here is that a dream is simply an obscure collection of information that you already know – thus dreams cannot predict the future (in any useful way) or any of that other nonsense, but they can be a manifestation of your current concerns.
I wrote this article with a post I had in mind where I interpreted someone’s dream for them, but unfortunately I think that person removed his post so I can’t use it as an example. Suffice to say it was an abstract desert setting in which he came under attack by mysterious riders, one of whom (the only one whose face he could see) was a beautiful woman. I interpreted the barren, primitive setting as an allusion to abandonment and isolation, the attack as a feeling of alienation and victimisation, and the woman as a latent sexual frustration. Combined, I saw the dream as a manifestation of the poster’s feeling of loneliness, caused by a constant lack of success with women, to the point where his automatic reaction to them was one of defence (they being the source of some pain), and the specific woman’s face to be indicative of one particular girl at the current time that he’s been thinking of. Naturally, I made this interpretation without any contextual knowledge of the person, which may have increased the accuracy, but surprisingly he responded a few days later that it was indeed very accurate and that he had been struggling with the exact issues I mentioned.
Anyway, the point here is he already knew he had these issues – so the dream in itself is only telling yourself something you already know. In that regard, it’s an exercise in futility to try and discover something profoundly important in your own dreams because the dream itself will only contain information you already know.
It’s interesting that the majority of dream interpretation involves some sort of latent sexuality. The majority of Sigmund Freud’s dream interpretation works involve sexual symbols (the snake, the number three, the playing of an instrument, etc.) as well as egotism. These are all really just indicators that behind all the pretense, sex and narcissism are hugely important factors to humans.
