How do you withdraw the impression from subconscious mind?

We are conscious of everything we are aware of,this creates conscious impressions in our mind,but when we are not conscious of,meaning we do not conceptualize or are not aware of due to lack of meaning our minds are set in a state of limbo as it seeks to understand.At this point thoughts become subconscious,and an unresolved question is posed in the subconscious mind.The answer to that question is the impression we get.
