She dreamt of Kelly last night. He was alive and working at a CVS. She had seen him at the CVS, but didn't realize it, because she had looked him in the eye, looked at him closely enough to note the black earbuds he was wearing and his frizzy hair, and had not recognized him.

She had gone to visit Kelly's dear friend Eric. As she left Eric's place, she saw the man from CVS in the driveway. He was calling out to Eric to tell him that he had seen her at the CVS and he was so happy. He was happy to have seen her even though she didn't recognize him.

And that is when she did recognize him. And they embraced. And he was alive. It was confusing that he was standing there alive, but she was so happy to see him. They were so happy to see each other.
 
When she awoke it was that feeling that haunted her, that he was so happy to see her. And it made her cry even though he'd been dead for almost 30 years The dream had made his happiness seem as real to her as her own.
