Ah, the phenomenon known as "coincidence." I have it from time to time as well. I'm sitting in traffic, listening to the radio, and suddenly I think about Katy Perry! And all of a sudden, I hear "Part of Me" or "Fireworks" or "Wide Awake" or "The One That Got Away," realizing full well that Katy Perry has dozens of hit records playing on various radio stations at any given time!
Well my example was of a natural disaster, which fortunately aren't occurring by the dozen, at any given time. And I've probably spent 20 minutes of my life in a cemetery in the past 10 years, so again not a common occurrence.
Funny enough I needed a photo of a wartorn room (don't ask) the other day, not the easiest (or pleasantest) of things to Google, and strangely there's not much online, tried fire damage, all sorts of odd searches. Then it occurs to me in the night - Earthquake! So I Google in the morning the first thing I see is there's just been a minor one in LA! Now obviously that is far more common, but at the same time its odd there was one at the one place in the US I've been to within hours of me thinking about one.
Oh sure its all coincidence - most cases you couldn't plan if you wanted to - but it doesn't mean they aren't frankly surreal.
Like once when I was reading credits in a CD, I saw one (uncommonly) named individual, then the next second a character on TV introduces himself with exactly the same name and surname!
Basically, what you're experiencing as reality is a reconstruction by your brain.
In deja vu it has been hypothesized that there's a bit of minor misfiring: Imagine every step in that process I just described happening except for the conscious reaction. Your senses perceived, your brain reconstructed a viable perception of reality, you processed that perception emotionally, but a little fluke stopped it from being processed consciously. No worries, because your brain is already doing it over again, senses perceive, brain reconstructs, you react emotionally and consciously. But now your conscious says, "Wait, this seems familiar..."
Pretty cool theory, huh?!
It's not sure it's quite like that with me, it's like I'm subconsciously aware of these little moments - weeks or months before they happen - like a loose bit of puzzle hanging around my brain. All of a sudden they slot into place and make perfect sense.
I had a vivid dream of going to visit a friend just a couple of days before her daughter killed herself. The dream was so vivid that it bothered me during the day after waking. Upon hearing of the death, the route I dreamed about, the one I had taken to see her before, was the one I followed.
I had a warning dream too once, though completely the opposite. In this dream someone whispered in my ear - 'she's pregnant'. Which woke me with a start, heart pounding. There was only one She it could be. One of my best friends, who I fancied rotten. So anyway, I say the next day 'I had the weirdest dream last night....' then she said don't breath a word, but she'd found out the night before she was. Even half her family didn't know. So the previous time I saw her, was she giving off signals even she didn't know about? Who knows. But it was nice of my subconscious to give me about 2 months notice before it became common knowledge.
One thing that does bother me a little is the last thing my nan said to me on her death bed. She either said jump, or she said don't jump. So if if I'm ever in a life or death situation where its an option, its going to play on my mind. The indecision could prove literally fatal!
