In my experiences and reading the experiences of the other I have come to one conclusion. Children are the ones who see spirits but can't exactly feel them and their psychic talents have yet to be developed. So that leaves me to questions, are children who see spirits psychic? Can psychic children see spirits? The answer to those questions I think are still a mystery. When my grandmother, I was age 8 or so and I saw her in my room. After that I saw spirits regularly. When I hit puberty, I saw some, and felt some, and started to be able to read and "know people" iv'e never met. From there, i'm 17 now, I can no longer see them, but I can feel them, and my feelings of people are stronger.
I have also learned that when extreme emotions or emotional exhaustion hits me, my psychic sense seem to be more sensitive like when adrenal starts pumping and you become more sensitive. Has anyone else noticed this pattern as well? To conclude I have a sister who has also seen someone close to her in the after life. The difference is when she hit puberty, she can no longer see or feel anything. When it comes to nature vs. nurture, we were raised the same as we are similar in age. Could it be in our genes? or the way our brain developed? Well who's to say? Anybody notice this pattern as well?
