There are many theories as to what causes déjà vu.One says that our "spirit" can actually travel faster in time than our earthbound bodies so it charges off into the future from time to time for reasons we can't explain.
Another claims that it's because we are reincarnated and old memories from past lives are seeping through into our current consciousness.
And then there's the parallel Universe theory that suggests our lives are always splitting off into different directions whenever we make big decisions and that at the point of experiencing déjà vu we are connecting with these parallel worlds.
All of which rather ignores the actual sensation of déjà vu that is simply joyous and mesmerising regardless of what it actually is.
Déjà vu experiences stay with us too, logging themselves into our memory banks where they can be withdrawn whenever those "déjà vu" conversations occur, usually over a few glasses of wine late at night!
"There's an opposite to déjà vu. They call it jamais vu. It's when you meet the same people or visit places, again and again, but each time is the first. Everybody is always a stranger. Nothing is ever familiar."
~~ Chuck Palahniuk
Visiting Norway in July 2010 and we stopped at this place for a short while, an eeriness came over me as I photographed this scene. I wanted to hop in that boat and paddle into the mist.
