With the advancement of Science we try to decode Unconscious mind and define it in terms ,which can be easily understood by the conscious mind.
Infact,the entire knowledge can be categorised as conscious or unconscious stuff.But with the level of understanding that we posses today,it is not possible to do the exact categorisation.
For example what we see from our naked eyes like Glass,Fan etc. can be categorised as a conscious stuff and various unnamed imaginations that we see during ecstasy,dream or in a special state of mind can be characterised as unconscious stuff.
Also,we have a full understanding of the linguistic sciences for the conscious stuff.But think can we ever develop a new linguistic science for the unconscious stuff.I call it "Language of Unconsciousness"
