Someone may have mentioned this already, but this part:

perfect strangers when we meet strangers on the street lovers while we sleep

just depicts perfectly how one acts when they see an ex. You pretend like nothing ever occurred between you two, you are polite (maybe) to each other, its somewhat of an act, because, no matter how long it has been, you are lovers while you sleep, because you don't have much control over your dreams. You dream about that person from time to time, and the intense feelings that were felt in the relationship are still there if only in dreams.

This also could explain the lovers out of time line, because if you dream about the lover, its like there has been no time that has passed. The restrictions of time and space have little do do with one's unconscious and/or subconscious mind when the heart/emotion is involved.

..Hit the Nail on the Head.. thats not easy to write about. props to you.
