T-Rex, Motorbikes and Musical Prisons

I'm on a motorbike riding around in a city that looks a lot smaller than it should, and chasing me is a T-Rex.

I weave through the streets easily avoiding the T-Rex as it charges after me. Then, for some reason I'm lying in an open top skip or giant bin......which is full of grenades. I'm hiding from the T-Rex as it walks by, not being able to detect me. Either because I'm lying still or I just blend in with the grenades?

I'm in a room with a floor that is both solid and viscous at the same time, and trapped in the floor with their heads sticking out of the ground are 5 people. A family I'm assuming, and to free them I must get them to sing, but they must sing notes in the correct order.

Like a conductor before an orchestra of heads in the ground, I successfully command them to sing, the floor becomes gooey again and they get up and out of their predicament, thanking me for freeing them.


I wake up.
