Panicking about seeing an ex

Date: 11/4/2018

So apparently I was travelling on some island and were on a mission trip. The place looks completely unearth like and there was a ancient looking showering point using pails to shower and next to it, there’s a palace-hotel like place. After I showered, I suddenly realise that my ex is in the vicinity. No one told me about it. I just randomly knew it. So I walked out of the showering point towards the hotel lobby and I saw my ex’s friend. She told me that my ex is around and asked if I want to meet her. I did not reply her but deep inside I was panicking and super nervous about seeing her again. But all these emotions come from fear. Fearing that all those bad emotions and feelings and all the hurt will resurface once I see her. And obviously I also feared seeing her possibly new bf. After a while, my ex’s friend walked away while a group of my other friends came, talking about a mission they have here. I was still worried I might see her during my conversation with my friend. Soon after, I woke up. P.s. The breakup happened more than a year ago and I’ve pretty much gotten over it (or so I thought). I don’t think much about her at all now although recently I did chanced upon some breakup posts on reddit which reminds me of her. Anyone knows what this dream means? Am I still subconsciously attached to her?
