Some people experience dilemma, wooziness and feeling that they might faint and vomit any minute. There are a lot of reasons, really. But what are the consequences? Some people are so drunk they wanted to sleep but can't or have fallen into half asleep but still aware of the sounds and breathing even the slightest movement of the cat. Some people are just bone-tired that there is a battle between consciousness and unconsciousness. Yes, the consequence is a continuous battle of the conscious and the unconscious mind.
The battle between the two minds is where the power of your subconscious mind begins. People could say that if there is a real war between the minds, subconscious is in the middle of the war intercepting or maybe, maybe, as a peacemaker. Subconscious mind is a topic that is unclear to most people. Also, it was not explained in a scientific way. The best way to explain subconscious is that it creates a conflict between conscious and unconscious but it also bridge that conflict. There is no telling if one can control the subconscious mind or if which mind it contradicts. Is it in favor of the reality or the dreams? More importantly, does it really exist?
If it could be proven in psychological or scientific way then it is safe to declare peace between conscious and unconscious minds. The power of your subconscious mind might something to do with seeking answers for both minds. If the two contradicts and in conflict then subconscious resurface thoughts that were clouded by both minds. It is possible that information obtained by people is somewhat lost its way. The subconscious acts as mediator of this information.
Also, conscious mind has overloaded information that it tends to fall its way to subconscious. That way, subconscious helps the conscious mind to distill the right information needed at the moment. Call it whatever you want. You may not control the subconscious but is always up to something.
In other sense, subconscious might be the one helping the unconscious mind to be more real. The power of your subconscious mind might be that it emerges denied by conscious mind like urges, habits and instincts. One could say that subconscious is people's irrational part of the mind. Or it is the devil in disguise while it contradicts the conscious mind into doing something they don't or deciding best not better. Have you ever had a time in your life when you said, "something tells me..." It might be for the good or for the bad, but at least there is a guide. Because of these conflicts, people see two narrow ways, left and right, which would the mind choose? There are choices. It is better to have choices than look at a one way road thinking that it will all be the same in the end with no choices at hand.
So maybe, maybe, subconscious is a giver of choices whether it could be explained psychologically and scientifically. People don't have to rely on it exactly.
