It was between seven and eight o' clock and then I was in time again
A shadow has passed over the curtains, a natural marker of time, which is then juxtaposed with the unnatural marker of time, the watch.
“And then I was in time again…” is ambiguous. He is waking up late (between seven and eight) he knows this ostensibly by the shadow’s location — he would know where it would appear, studying it each morning. He is literally entering waking life out of sleep, one meaning of “in time.” Another meaning is he is back in “Time” — the awkward and inexact manmade milestone of life and death. This will be represented by the watch.
