Dream About Seeing Ex In Work

I dreamed of seeing my ex again in his current work. He work at sales department in one of Landers grocery. It's a matured conversation. I'm not angry just checking what happen to him from the last years we are apart. He is a big part of my early 20s and we lost communication during pandemic and after almost 5 years of relationship he ghosted me. No explaination why he want to break up with me. Never had a chance to fix the situation. I chase him for 3 months before giving up our relationship completely and to this day, that's my biggest what could have been? In my dream, I was a customer of Landers and I stumble upon his associate and I was asking for something then he a approach me. He talked to me and he told me about his journey.
