Why did i Dream about a ex after a year

Abby

So my ex was my friends brother I’ve known both since the 2nd grade (I’m 22 now )

Last year we broke up it was very messy and I lost my mind wen he left me after I begged him 2 years before to leave me cuz I was to weak to leave myself ( he’s very about himself and wat makes him happy I feel he’s a trues form of a narcissist ) cuz I’m not a irrational person but when he called me saying he wanted to work it out I drove 30 mins to see him just for him to tell me I was to ugly for him and he was leaving me , I ended up smashing his windows of his car in and took out all but one tire , I have never behaved that way in my life I just snapped and if I had have the knife wen he told me that I prolly would’ve stabbed him tbh that’s how crazy I was

But I moved on I found a lovely man and now after this time I have a dream about him and his sister who I stopped being friends with because she proved to be untrustworthy and to me trust is a big deal since my past was so fucked up

** all the dream was my ex showing up crying and me and my ex friends arguing about not being Trust worthey
