I've only had a few dreams that featured film photography (or parts thereof)
Once I dreamed I stole a roll of kodak film (120 in a black wrapper) from a museum...

In another dream, I walked into a camera store, they had a sale on ALL there old paper...boxes and boxes of the stuff all in pinkish packaging, filled my entire car in this dream, and I paid almost nothing for it.

There was the one where I bought a "new" Ilford film "FP6 Velvet", but the box was black like the previous Ilford boxes, and the lettering was maroon. I shot this in black Leica M6 in Cape Town. Too bad when I woke I had neither the M6 or FP6 Velvet and didn't live in Cape Town
