6th sense who has it? who needs it?

The idea that humanity is capable of perception beyond the empirical ones, sight, sound, taste, smell, and touch, is one the pervades and questions our beliefs about the world. The belief in a sixth sense that perceives that which our other senses fail to recognize exist to some degree or another in both secular and religious discourse. you need not be a theist to believe in human's capacity to exercise their sixth sense, however, depending on your beliefs you may perceive the cosmology, origin, and teleology, purpose, of the sixth sense differently. In the Judeo-Christian traditions we learn that man was once capable of a sixth sense and that involved their ability to see and, beforehand, interact with spiritual beings who now reside in heavenly places. moreover, since the fall of man our connections to the spiritual world was strongly severed and our 6th sense was extremely weakened as well. Consider for instance how damage to the body can weaken and sometimes destroy any one of our sense it would then stand to reason that moral or spiritual fractures can lead to a lost of our spiritual senses.
              Dreams serve as evidence in our connection to the spirit world and our ability to access our 6th sense. Many indigenous cultures and faith believe that dreams are significant or can serve as a spiritual guide to understanding our material world. For instance, in class some of us shared similar stories citing a time in which one of our dreams led us to become seers of a sort, intuitively knowing something that was to come. In my particular case after dreaming i was able to determine, without a doubt, the truth of my aunt's passing.
              Deja Vu is a secular example of what it may mean to possess a sixth sense. Often people come across a person, come into a place or even witnessed something that made them feel or have an intuitive inclination towards that thing with no active memory of that thing. Deniers of the 6th sense suggests that deja vu is little more than an anamoly in the memory portion of the brain. Many believe that the enlightened few who are aware of the supernatural plane around us are gifted and special. The few who possess this gift portray it in any number of ways, prophetic vision, vivid dreams and even astral projections. The most fascinating and conflicting part of these ideas, for me at least, is the forever conflicting knowledge that a physical world exist as well as a spiritual one. The pious one might argue that since we indeed possess a 6th sense then dreams must have meaning and visions are a symptom of being chosen by God. While the religious skeptic might suggest that these things we claim and take to be part of a spiritual dimension is false and he or she who claims to be having visions is perhaps mentally ill. My personal conflict is that given both do in fact occur how does one determine the difference at any given point.
