Short Stories with Tragic Endings

I am with a representative of Puma who seems to resemble a cross between
Bear Grylls and Mike Rowe. There is also an old lady there. They are doing an
experiment with Puma's newest shoe, the Cabana Racer, and the representative
gives the old lady a red and orange pair of Puma Cabana Racer shoes. I point
out that I am also wearing my white-black-grey pair and the representative gets
a smile on his face and says "aahh". The old lady puts on the red Pumas and
the test is going to be a race with a race car. The car is yellow and looks quite
fast. The old lady starts running and I run as well. The car is definitely not going
its full speed but it is not going slow either. Somehow we are keeping up with it
but we are not going faster than a normal running pace. We run through a city
for a while, the car had lost us a long time ago, and after a bit we stop, look at
each other, and the dream ends.

I am in an unfamiliar place. It is difficult to describe but there is a tall metal structure
with a ladder running up through it and clues to the next place to go. It's like a race only
the course unknown and this tower shows the path. I remember several of my friends
being in this race with me. We had to run around a building and I began running. I was
able to run normally and I started pacing myself so that I would be able to make it. The
person next to me went all out. I resisted the urge to match their speed, that they would
run out of breath and become tired. Sure enough, they did and I came around the building
first. but then one of my old high school teachers was there with a bunch of my friends
and she said something like "You have to wait". I forget what the reason was but making
it there so soon was for nothing. After that she let everyone go and I went back to the tower
climbed up and looked for the next "clue". I then suddenly found myself in some sort of lift
car sitting next to a couple of my friends. I was thinking of my crush and my one friend who
was sitting next to me said "Why do you like her and not me?". I think about this comment
but say nothing. We ride on the lift for a while longer and the dream ends.
