This isn't about hallucination – that I'd be worried about. I'm not seeing tangible, 3-D evidence before my eyes of places past explored. It's more a fleeting rush through my being that the quality of the air, the light, and my inner state have somehow aligned exactly with certain moments in those places.
Waking the other day, I heard church bells in my neighborhood that I'd never noticed before. For a second the bells and I were in a little hillside town, looking perhaps at a map or a guidebook during breakfast and wondering what lay ahead. A feeling of freedom and discovery washed through me, even though it was a work day. The sky was blue, and the day promised to be pleasant and of my own making. I was in a new place with nothing but my interest and energy, ready to explore a new, strange place and be thrilled. A few seconds later, I was home.
This happened a couple other times recently, once when I was driving to nowhere in particular, and another time on a walk. Perhaps it goes back to resonance: enough elements in the current time line up with the qualities of the one I had before, elsewhere, and the tuning fork is struck. Deja vous doesn't describe it; it's not a duplicate of something that already happened. It's more a felt sense in the body than one in the head. Perhaps it has something to do with quantum mechanics. Maybe it's something about a time wormhole that is joining current moments with ones already lived, and I'm having trouble distinguishing which year/life/place it is – because in theory, past, present and future – and location – are all of the same package.
The possibilities are mind blowing. Considering them makes life more fun, and interesting, than throwing out every idea that doesn't immediately make sense. All I can tell you is that I will never forget the morning I woke up in my sleeping bag on a campout when I was eight years old. It was the only time I have slept in the open, on the ground. Just before I opened my eyes, I was in the jungle, the cacophony of parrots and other animals around me, humidity steaming in the shafts of light that pierced the canopy of the rainforest.
When I opened my eyes, I was in the wide, grassy field just down the street from my house.
To the best of my knowledge, it was not a dream, but I didn't know what to make of it. I was young, a factor taken into consideration when revisiting the incident at a later date. But I also vaguely recall having the mental ability to "shrink my consciousness" into my thumb when I was a toddler. I would toggle it back and forth, saying to myself, "little, big, little, big." What this was all about, I have no idea, but clearly I was able to distinguish between two different states that felt like more than words.
It's too bad I can't travel back through some wormhole to childhood to see what was going on, before life closed the mind off to certain ways of experiencing. I'm not the first one to say it – but isn't it a kick that children may just be masters of the quantum universe without even knowing it.
