Choose Your Masques / Dream Worker

I have come but I do not choose now
To do what I came to doNavigation computer report
Orbital status now maintained
Target zone vectors logged in
The Tube is now readyPlease swallow your Blue Dreamer
And place the helmet on your headCan you hear the lights approaching?
There's a sudden rush of sound
You laugh but no one's joking
The Dreamer's turned you round
And now there's no distraction
