American Dreamer: I Don't Recall the Specifics

Somewhere that night, either at my friends house or along the short walk home, I'd lost the bracelet I was wearing. I was sure that I'd had it on at his house - I remember playing with the loop-to-knot clasp. I must not have pushed the knot all the way through the loop. I called Chris and asked him if he saw the bracelet anywhere in his house - he didn't. This meant I'd have to go searching through the dark along the path I'd walked, hoping to find it. And it was late. And I was tired. So I went to sleep.
That night I dreamed about my ex-boyfriend. We were fighting and I remember a struggle to get out of his car.
When I woke up I cried. I didn't write the dream down because I didn't want to remember it. The message had been clear - get out of that relationship and stay out. I was out, I'd been out of it for weeks. So then how is it that three months after I lost the bracelet, he is handing it to me. The clasp is secure and it looks as though the bracelet was cut. He said he found it in his car - that I must have left it there. There's no way - I know when I lost it - it was on the walk home from Chris's house.
It's so inconsistent and strange. Had he been following me? What was that dream? Was I wearing the bracelet in the dream?
