Why am I dreaming about him ?!

Ok so me and my ex broke up November 2018 a week before our anniversary. (Because he cheated) December 4th I woke up to him standing over me . Drunk . In my house at 6 am (he used his old key ) . He told me he was sorry for all the things he had done and told me get dressed and we were going on a date . I told him he needed to sleep that drunk off . He slept 2 hours at my house . Then we went out to see if there was anything there from what I agreed there wasn’t . We did have sex that night tho it was great and so was our day. But I ended up blocking him .

I started dating again March 2019 and found someone else soon after . We’ve had our ups and downs but been together since . May 2019 my ex popped up at my house because I had his number blocked we talked maybe 20 min . Caught up. He told me he spent some time just fucking women before dating the girl he cheated on me with and I’m like cool I told him I’m was dating too. Talked about new job he had and how I was back in school and before he left he wanted me to text him I said I would but didn’t . October 2019 my ex showed up at my house AGAIN (mind you we didn’t txt talk or nothing since may) showed up with flowers was saying he wanted me back and stuff like that . Told me break up with my bf . Said a bunch of bad stuff bout his gf . Said his mom ask about me . Etc I was laughing the entire time . I declined but he wouldn’t leave till I atleast took the flowers so I did and sent him on his way . (We stood in the door way like 25 min )

February I post “let me not tell this fool happy Valentine’s Day 🤫🙃” and my ex’s gf messages me saying if you plan to don’t . And I’m like do I know you ? And she’s like I see my bf txting you and hiding what you say back (mind you again he’s blocked so I definitely wasn’t texting him ) so I tell her bout herself and blocked her while she was typing . The post wasn’t even about him .

My bf knows about all of this . I told him the day of each event . We did argue in February because he accused me of texting my ex because he pops up when he’s not around. I’m like he’s just popping up randomly and I’m not texting him at all.

Well 2 nights ago I dreamed that I was at my bfs concert and my ex jumps on stage and pours juice on the crowd . And last ight I had a dream I was buying camping supplies and brisket in a white shed and I run into my ex and we catch up and I’m the one that wants to be back with him this time he tells me he’s engaged to the same girl.

What does this mean? The last time I thought of him was april because I had a picture that popped up in my Snapchat memories where we went on a trip and saw black panther at this fancy 3 story movie theater . So it’s not like I’m thinking of him before bed and that’s why I dream of him .
