That dream which we recalled was us interrupting our subconscious as it processed information on our behalf.
Whilst our subconscious mind can use the same language as we do in everyday conversations or thinking to ourselves in our conscious mind, it does have its own language and it uses that language to sort things out for us.
Our subconscious mind speaks to itself using the language of Metaphor. In that way when we have a problem no matter how complex the problem is it can convert it into a complex metaphor and so be able to divine a way forward for us. It might be a month or just a week after we have been worrying about some obstacle or problem when hey presto, a solution to our entire problem will suddenly pop into our head. We might even become annoyed at ourselves for not having figured it all out before. But, we did not figure it out with our conscious mind going over and over it all as we did to no avail. Meantime, our subconscious was quietly constructing metaphors and building a solution for us.
Whether we are a genius or a fool our subconscious will never be wrong. And so we return to the Tarot. Tarot cards are pictorial representations, in short they are complex metaphors, the very language most favoured by our infallible subconscious minds.
When the Tarot Therapist shows us one or two Tarot cards they may ask if one of them holds a significance for us. Almost always they will, because whilst we are thinking there with our conscious minds, our subconscious has performed a swift reality check and flagged up a significance into our conscious mind.
In that way the client of the Tarot Therapist will have had a new insight into some niggling problem or maybe had their view of what might be expanded. In those and other ways the therapeutic value of the Tarot should be taken seriously.
