While ardently pursuing the faint hope that I would someday find a
"scientific" (physical) explanation for various "psychic powers", I have
experienced several remarkable events that would appear to be "impossible" 
by our usual standards. The events are not "big" in terms of the impact
they have on our lives, but the non-linearity of time implied by these
events gives rise to serious concerns about the "stability" of our
universe, as we know it. 

For years I have been noting how, occasionally, people insist on 
remembering specific events in a manner that disagreed with my own 
memory. Until recently, I had assumed that one or the other of us was 
simply mis-remembering. Now, I'm not so sure.

The critical event that drew to my attention the notion that reality could
"shift" was when we borrowed a friend's video boardgame. The game comes
with a set of six white plastic tiles, each approximately a centimeter
square. Each of these is numbered from 1 to 6. At the beginning of play
each player draws a tile at random and places it into a slot in the base
of the playing piece, displaying the number. 

About a month after first borrowing the game, while putting it away after
playing, my lady stopped and said, in a very confused tone, "Hey! I
thought these tiles only had the number printed on one side!???" 

I "knew" for a fact that the tiles only had the numbers printed on one 
side, yet when I looked at the tiles they quite clearly had the numbers 
professionally printed on both sides. I have clear memories of the tile 
only having one side printed, even to the point of both of us remembering 
when I made a silly joke of inserting my tile into my playing piece blank 
side up. Our daughter, aged 7, also remembers the tiles having a blank side.

A REAL oddity is, when we returned the game to its owner, they insisted 
that the tiles had always been printed on both sides. That is, it wasn't 
just a physical change, but apparently people's memories, except for 
ours, seemed to hold the two sided tiles as the only kind that had 
ever existed. 

Another good example is the incident where I placed a two liter pop bottle
into our fridge-top freezer compartment to chill quickly, and then forgot
about it while I went out to buy groceries. Upon returning to our home, my
lady and I proceeded to unpack groceries, and she watched as I grabbed a
box of ice cream, opened the freezer and placed the ice cream in the rear
corner where it would be coldest. I closed the freezer door, dug into the
next grocery bag, found the frozen orange-juice and this triggered my
memory of having put another drinkable object in the freezer. I opened the
door and there was the bottle, right in the middle. And there was simply
NO physical way to place the ice cream into the freezer without having
bumped that bottle. There was certainly no way for me to place the ice
cream into the back corner in one smooth fluid motion, as I remembered
doing five seconds before. And my lady saw me do this and agrees the pop
bottle was NOT visible at the time I put away the ice cream. Even if we 
assume that I MIGHT have somehow removed the bottle to put the ice cream 
in, my "trigger" for removing the bottle was sensitive enough that 
seeing/touching the bottle would have prompted me to remove it. That is, 
I could not have handled the bottle without it intruding upon my awareness.

These are simple, clear-cut, unambiguous examples of a phenomenon that has
occurred more than once in our household. Most frequently my lady
remembers me doing/saying something which I not only do not remember
doing/saying, but which is actually contrary to my nature/habits, such
that I *would not* do or say the thing she remembered. On other occasions,
my lady and I remember something that someone else said, but that other
person just as clearly didn't say what we remembered. With the exception
of the tiles and the pop bottle it has been very easy to ascribe these 
occurances to faulty memory. Or at least it was......

Now, I consider it important to distinguish the phenomena I am describing 
from simple "apports" - a term I have seen used to describe the 
"mysterious" disappearance and reappearance of objects. Prior to the 
incidents with the tiles, I had already accepted that occasionally a book 
I clearly and unambiguously left on a table top has turned up in a drawer 
half an hour later with no one in the house to move it. Or keys would be 
gone from a pocket and sitting on a table top even though they had been 
placed in the pocket minutes before. But reality shifts are more than 
just objects popping in and out. It affects the physical evidence and 
memory of events that supposedly occurred in the past, in such 
a manner as to suggest that the past itself has been changed.

One store we visited "did not deliver", but when we returned the next day
the same woman who had told us this insisted that they "had always
delivered". A restaurant where we had made reservations many times
suddenly told us that it was policy to never take reservations and they
had "never" done it! The simply couldn't understand our insistance that we
HAD done it before. We used to think that people in situations like this
were liars, or were covering for some mistake by changing their story. 
But consistently, there was a feeling of honesty in what people said to
us, and so we accept that reality isn't quite what it used to be.....
