Well, it's long since been proven we as human beings have a sense beyond the 5 physical ones. The "6th Sense" is real. That is the sense beyond the physical self. That feeling, perhaps, of being watched when your back is turned to said watcher. That feeling mothers get sometimes when their infant is in distress and calling out to them. An intuition that goes beyond sight, sound, taste, smell, and touch. It's real, whether you chose to believe it or not. It's called extrasensory perception and though it's stronger with some people, all have it.
Myself, my mother and my grandmother are all proof of this. Apparently within us is a higher concentration of electrical energies, which gives all of us a very strong aura. This aura effects devices which we wear, given that we wear them long enough. These devices, watches are the most common example, simply stop working after about a year of wearing them, even those with battery life guaranteed to be longer than a year. Apparently our strong auras suck the electrical energy out of the watch battery, siphoning it slowly until the battery no longer holds a charge.
Auras are strongly linked to the 6th sense, in case you're wondering how this all links up. The stronger and more receptive our auras are to the energy around us, the more likely we are able to perceive with it. In fact, some are able to see the auras of other people. I admit, I don't have this gift, per say, but I can sense auras and if I close my eyes, my 6th sense can allow me to feel the aura and in my mind chakra or the third eye, I can see it and all it's blemishes. If I concentrate my energy and mind hard enough, I can even extract the blemishes from the aura and allow it to flow freely, thus opening up the chakras.
I hope this evidence I put forth helps in someway prove to those nonbelievers out there that there is a world beyond the world we sense in the conventional way.
Have a good day!
