Time Line

Flying along a thin line, red coloured, on the ground.
Faster and faster, past my birth, Primary School, High School, working as a telephone engineer, weather man, faster and faster, loads of little land marks, goals achieved or not achieved . .
On and on . .
Too fast, try and retrace . .
Only works One Way?
Oh no!
The final lesson?

Time line

A short but vivid dream last night of floating along a thin line. I looked down and could see another fuzzier line which had hours marked on it, although not very clearly. I was aware that I could float downwards to, say 7am, and then I would awaken at that time. I was in a slightly lucid dreaming state. Also aware of a friend nearby watching me and perhaps a bit concerned.
Wondering now of course if it was uni-directional, could I reverse? Could I speed ahead? Maybe not possible or allowed.
