Firstly. . . I ask you to PLEASE use proper sentence structure when you write (capitol letters where they belong) so I can better understand what you're saying. As it is I feel like I'm reading one very long sentence and no paragraph breaks. It makes things difficult when it comes to my personal ability to absorb things; my health issues make it hard enough (especially lately) but coming across grammatical structure of this sort, simply makes it much harder.
Being Religious or Spiritual (which are two completely different things) my not be your conscious perspective of self, but there is a past in which this was very much so and it is that past that makes be believe that you have a natural propensity for clairvoyant type abilities or "sensitivity" as it were.
Clairvoyant & Clairaudient people are able to see and/or hear (or both) things that are distant or "concealed" as far as the general public would be concerned. In the past people have been give credit for having a kind of X-Ray vision because they could tell you what was inside a sealed box or even buried canister. In your case, there seems to be a past-life skill that you have brought with you into this incarnation, it's just not as developed as it probably was previously, which explains why you are only seeing the shadowy images. As I said before, what you are seeing peripherally is probably similar to seeing humanoid shaped shadows cast upon a translucent fabric or heavy "dull" plastic even, that you can't see through clearly. This is the veil I spoke of earlier.
The Veil is a rather ancient term used to describe separation between the worlds or planes of things mundane vs. spiritual. The Temple of the Jews for an example, has a Veil that separates the Holy of Holies -- where the Arc is said to sit -- from the common patron and even the majority of the clergy. You will find a similar practice in Catholicism and some of the spin-off sects that still restrict sight and access to an area behind the altar. These are carnal expressions of this veil. Legend even states that when Jesus took his last breath that the veil in the temple fell or was shredded and thus, the essence of the divine was released into the world for all to know vs. being an exclusive to priests. Then again, there are many bits of folklore tied to said event, much of which church authorities simply discard as conjecture. But, there are other veils when it comes to the mystical, all of which tie-in with the idea that a special truth or set of gifts exist for those that step behind the veil. Some children for an example, are born with a thin layer of skin stretched over their face that is easily removed by the midwife or doctor, but the presence of such a thing has historically been a sign that the child is "chosen" and will do many miraculous things in life. . . and in some traditions, means the child is "evil" and must die. Then again, being able to see and know things that are believed to be secret and hidden, could make certain people of power nervous and said person having said abilities, a danger to them. It only makes sense to demonize them, create a myth that results in panic when you see such and the ingrained understanding that death is a must, portents being what they are.
IF all these things are true to you, the time will come that you will have to choose a path in which you seek honest understanding of them and thus, you will willingly walk through the rituals needed for opening the veil for you and helping you to better understand its purpose and more so, their purpose in your life. I'd say, this being the case, that you are already walking down that path in that you're asking questions.
BEFORE you move too far down the metaphysical course of things however, I strongly suggest more psychiatric testing and consideration. I personally don't want to lead you down this path if a genuine medical explanation is extant. If, on the other hand, nothing seems defined via such testings, I'd be more than glad to set you on the path that will help you gain clarity and move you along the path of discover, when it comes to this phenomena and understanding it, metaphysically. Understand however, I'm nothing more than a pointer and not a guide. As you are ready others will come into and mover out of your "reality" and when you are ready, the real teachers will reveal themselves carnally as well as within your dreams.
The next steps are entirely up to you. Regardless, enjoy the journey and what it has to share with you.
