oh, two dashes is my substitute for em dash, and the / only indicated a line break. ie,
I drifted in and out of sleep -- my dreams became the sky:
a silent movie melded from the pageant passing by.

On second thought, it's unsatisfactory. I would suggest this now:
I drifted in and out of sleep. My dreams became the sky,
a silent movie melded from the pageant passing by.
or
I drifted in and out of sleep; my dreams became the sky,
a silent movie melded from the pageant passing by.
As far as I recall, semicolons separate, when not listing, independent clauses, so it's more appropriate to separate these two lines with either a colon or a comma.

Hi river,
you are as you know absolutely correct on the semicolons use to separate independent clause....that is to say it SHOULD be so used...but, it can also be used to introduce a structured pause longer than a comma but shorter than a period. I use it here to indicate a pensive ponder, as if the character had just thought of the silent movie metaphor. Frankly, you are more right than I am wrong...I need to think on it.
Best,
tectak
