I'm narrating a story about events which happened yesterday. I'm looking back on completed events, so I use perfective.

Suppose I write: 

{wa'Hu', qaStaHvIS wej rep, jIQuchpu'}

What does it mean ? "yesterday, for the duration of three hours, I've been happy" (i.e. my happiness lasted three hours), or does it mean that during those three hours, I was happy only once (for a period of time shorter than three hours, e.g. a minute, an hour etc) ? Or can it mean too, that I was happy more than once, i.e. my happiness going on-and-off ?
