I'm so glad I found this site; before now I thought it was all just random crazy that I was experiencing (though apparently this has happened to my mother as well; I'll come to that in a moment.
It started, I suppose, back when I was around seven or so. I was always a quiet child, and would play for hours in my room with my toy horses and legos. Sometimes I would find myself daydreaming, only the things I would envision were not the usual things a little girl dreams about; instead of receiving a pony, I would be watching my father do housework or hearing mother talk on the phone with my aunt. I would think very little of it, simply going back to my place once the reverie dissipated. The next day, however--sometimes even two or three days thereafter--I would find myself witnessing the very scene I had daydreamed about. My father would be doing housework--an odd occurrence for him at the time!--or my aunt--with whom we did not keep closely in touch--would call, and as I had foreseen mother would sit in the kitchen and talk to her. I made no mention of this to anyone; I assumed I was just crazy.
Then fast-forward to the year 2001. I was sitting at my desk one evening, doing my homework and again, I fall into that haze and begin seeing things. This vision was odd even by previous standards, however; it depicted what I initially thought were smokestacks, all slowly collapsing, kicking up massive brown clouds of dust and smoke. People were running every which way, screaming and coughing and crying. 'I can't breathe, I can't breathe!', one lady cried. I was disturbed by this, but assumed I was merely up too late and having odd dreams. The next day I was in gym class, preparing to help my partner do sit-ups, when I was called out of class and given over to my mother--she quietly informed me that there had been a terrorist attack, and she wanted all of her children where she could see them. The date? You guessed it; 9/11. At home I watched the footage from the Towers collapsing--and recognized the dust and smoke clouds and screaming people running blindly.
I once got up the nerve to talk to my mother about this, and she said it's actually more common in our bloodline than most. She started seeing things, as she termed it, when she was a little girl. She once had a vision of her sister-in-law and her both holding a blue-blanketed baby, whom she assumed would be the outcome said sister-in-law's fertility treatments. One year later, however, both had a son of her own, and my mother would have another boy two after that.
I also had an experience in which my late grandmother's voice awoke me, and something unseen sat on the edge of my bed only to depart moments later.
So, those are my experiences. Forgive the rambling; my question is this: precog y/n?
