You may have seen a trash unit being ejected from the ISS (they fall and burn up in the atmosphere, but can move around quite a bit)...or perhaps one of the electrical experiments where the long “canvas” was eventually cut loose.

Nope, the orbit of the 'whatever' was nowhere near the Shuttle or ISS. It was a single point of light doing a jitterbug moving in a rough northeast to southwest direction that would bisect the Shuttle and ISS orbits, not parallel them.
