What is the philosophical take on the subconscious and who came up with the idea

What is the philosophical take on the subconscious and who came up with the idea? It seems highly problematic to me in that its existence can never be established because of its very nature. It is rather like positing Pluto to account for wobbles in other known planets' orbits except that Pluto can be demonstrably found! This is different from the unconscious mind which keeps you breathing, etc. which works rather like the programmes running in the background on your PC. No mystery here. And where do dreams enter into this debate? I can't ever recall having had a 'symbolic' dream, just ones dramatising traits and memories I am well aware of. A statement like 'I hated her but I now realise I subconsciously loved her' is surely just hindsight. Knowing and not knowing something at the same time has to be impossible?
