subconsciously what? they don't MEAN anything. they are a product of your mind, so, stuff you've been thinking about or dealing with might project itself during your sleep, but you won't get special dream-wisdom out of it. dreams are what happens when your imagination runs off on its own without a conscious self to rein it in. it's random and meaningless. it's not your subconsious TALKING to you, it's your subconscious... clearing its cache.
