Dreamt about the train I took to class every day.  It was a pretty
long ride, like half an hour or so at pretty high speed.  One day I
got a little screwed up when getting on (this happened at the top of a
platform that I took an elevator to get to; there may have been a
brief getting-off on the wrong floor, too) and ended up riding on top
of the back of the train instead of in it.  It was one of those
smooth, aerodynamically-shaped trains, so I was holding myself on by
the stickiness of my palms on its smooth, yellow, metallic surface.
It wasn't that difficult to keep myself from flying off even at high
speed, but it was growing tiresome.  I found some handles to hold onto
instead as it passedthrough an urban area.  I sometimes had to watch
out for low bridges by scooting myself farther back.

There were some guys in a rocky desert place (which the train passed
by) making music with (A) a horn, and (B)many sticks of bamboo, which
were pounded against rocks by a bunch of guys with their arms fully
extended.  It looked uncomfortable and painful, because their knuckles
must have been hitting the rocks, too.

Later there was a junk yard and a bear.  A section of road that I was
used to traversing during my ruotine travels (i.e. to work or school
or wherever I was going) was closed off and the junk yard was
expanding into it.  But it was a fun junk yard, and I was still able
to bike across where the road used to be.  And at some point a baby
black bear showed up and some idiot was going to try to pet it.
