Actually, I've had a few dreams that made perfect sense. Most of them
were rather short, though.
A very memorable one was when I dreamt about a troop of militia
marching through a village, singing with full-throaty voices, to the
tune of "She'll be coming 'round the mountain when she comes." I
can't remember most of the words any more, but I can still vividly
recall one line: "We will all hang around till she comes."
Just after this line was sung, someone standing next to me said, "Any
time you have a song running through your head that you can't get rid
of, just remember this scene and it will drive it right out."
And it works! I dreamt this almost 35 years ago, and this remedy
still works if I keep recalling the scene long enough.
The only hitch was that after about ten years of applying this remedy
hundreds of times, the song "She'll be coming round the mountain when
she comes" began running through my head each time, but fortunately I
found another one that got rid of it fairly easily, and now I have a
little repertoire of old songs which together can stop all runnings
through my head.

Actually, some of my dreams do recur, so to speak: some seem to pick
up more or less where another left off weeks or months earlier.

I'm with you all the way on this. I often tell people on Usenet that
reality is timeless when they complain about me replying to old posts,
some of them almost two months old.

Different parts of the body are an environment to other parts.
Despite this, the unity of the body is just amazing. Why, for
example, does a pain feel like it is in my index finger when I hurt
it, rather than in my brain where the signal from my finger goes?
The signal doesn't register consciously until it is in my brain.
Otherwise we would never experience our hands jerking back from hot
things before we consciously feel the heat itself. [I posted on
reflex actions of this sort on another thread late last night.]

I'm not sure what Dale meant either, but I've given one coherent way
of interpreting that last question.
