Communicating with the subconscious

I have a question about meditation, but not sure if this is the right place to ask. In my experience, sometimes solutions for our problems come to us after a long day, when our conscious brain (higher cognitive functions) is too tired. Or another example, some people are highly functional alcoholics, or use drugs to supress their cognitive functions and get creative. (This is not a recommendation) Creative as in finding clever solutions to technical, engineering, science problems, but also artistically creative. This made me think whether we are a horse and a rider, or more like a vessel for our subconscious. For example 2-300 years ago, we still believed that our limbs are moved by our will, and we didn't acknowledge muscles. There is a clear tendency that we are biased towards crediting our ego. Different individuals have aspirations for different things, these aspirations spring from somewhere. Is it possible that our subconscious have more intelligence than a mere ask question - provide answers, memory recalling machine? If so, wouldn't it be great if we could communicate more straightforwardly with our subconscious? The question is, how should somebody go about it? Would anybody be able to provide some information or point me in the right direction on how this could be achieved through meditation?
