Maybe there was a rollback on the server responsible for your part of The Matrix?
On a more serious note: for a couple of years, I travelled to my parents' place every month or two. A rather tiring journey about 4-5 hours by car, most of it on the motorway. On several occasions, when looking at the road signs, I realized I had no recollection of long sections of the motorway that I should have passed! Even when concentrating, I couldn't come up with any memory at all. I'm pretty sure I wasn't asleep - at least not for that much of a distance.
The only explanation I have is that I passed those sections so often, my brain simply didn't bother to record those parts again, as long as nothing special was happening.
Later, I noticed similar occasions when driving to work - a much shorter distance. But most often, when I concentrated on it, I still could remember something.
As for passwords, I occasionally had the experience that a password I often typed without thinking suddenly didn't work, and the harder I concentrated what it was, the more difficult it was for me to remember the actual password. It was like the process of concentrating interfered with my motor memory that let my fingers do the work without actually remembering the password as such.
I blame it on old age and forgetfulness. I now use a password manager and never had that problem again.
As for Alzheimer/Dementia: as long as you can still recognize (and name) your relatives when you see them, and no one reminds you that you 'already told me this 5 minutes ago', you shouldn't worry too much. 
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

That's precisely right!. I had to let it settle down and collect the password.
When I tried harder, it was getting more murkier.

Went there because I had a similar issue.
Q. How do you transfer photos from an iPhone without using their POS application?
A. Don't you own a digital camera?

The OP has got class though, see his response.
WTF do they tout their oh-so-wonderful camera on a phone that is unparalleled in the known universe for then?

Looking at Marc's early work on the commodore 64 raised the following question?
Why do we seem to use i and j for loop variables?
Where did it come from I wonder.
And no I have not tried to google it!

Because there is a little bit of FORTRAN in all of us?

And everyone who wrote the early tutorials were probably steeped in FORTRAN conventions.

And the professors who taught us - or those who taught our professors - have a lot more FORTRAN than us so it's a cycle. Add the fact that i and j are short and as good as any single letter...

I think it comes from Fortran, where, at least originally, the letter defining a variable also defined its type. Any variable starting with I,J,K,L,M, or N represented integers. i & j, being the first of these, just followed through from there.

The answer is obvious. What should be used instead?
a & b?
o & p?
We aren't barbarians are we? i & j is just being civilized.
I remember wondering about it too but didn't delve deeper than letting that thought pass.
Sometimes I use a name instead if its short and descriptive otherwise I try and comment.

From FORTRAN. Variables starting with the letters I thru N were implicit integers in FORTRAN, and were therefore used as loop counters by default.

To add to what the others said about FORTRAN default variable types, variable names were limited to 6 characters as well so short variable names were a good idea. It was a convention that "generic loop counters" were I, J, and K (no lower case in those days, either!)
In addition, lines were limited to 80 characters of which the first 6 where for label numbers, used to target lines with GOTO and suchlike flow control; and the seventh was for a "Continuation character" which allowed you to use more than 72 characters in your code statement.
Short names were a good idea in those days!

Short names still are a good idea.
As a general rule, I'll use initials for temporary variables in loops etc and as the scope gets greater increase the size and detail of the name.

In the east we traditionally used n and m. And p and q for pointers. It wouldn't surprise me if it was just to be different from the decadent west.

If you took the Fortran IJKLMN, are the letters in the same order when translated to eastern languages? That may explain why your typically using n/m.

It might have come from FORTRAN, but "i" was also used for short of "index". When using nested loops the next letter was the most obvious ("j", "k", ...)
For me personally it makes perfect sense in some way. If you see a one letter variable in code, there is almost a 100% chance that it is a loop variable. Also a one letter loop variable in an array indication (some_array[i]) is easier readable than (some_array[index]). (though that is perhaps personal taste)
