What are former partner dreams about?

A quick back story.

I am currently quitting alcoholic and have been getting support through AA due to alot of bad decisións and finally hitting rock bottom. I think my son is picking up on this as out time together lately has been amazing without my addiction been present.

My ex partner just messaged me saying that my son has a dream where we had gone to the beach and a big wave hit me.

He said that he was happy in the dream so I don't think it scared him, I just wanted to know the interpretation of this if anyone can help.

Thank you in advance.

I’ll tell the whole dream here. If anyone is interested in interpreting it, I‘ll really appreciate that!!

It was the end of the world. The weather was going to kill us all, scientist had been tracking it for years. The end of the world was at 2 pm. I was in a street full of shops. The weather was going crazy, and so were the people. There were people driving around shooting people. People who always wanted to kill but could never get away with it. One drove by me and I asked him to shoot me because I didn’t want to die by the weather. He did, and instead of waling up I just became a ghost.

So I found a close friend of mine and followed her. The police were directing everyone to a stage, so that’s where she ended up. On the stage was an ex-toxic friend of mine. For some reason this friend could see me, she tried to hug me but I just walked through her and ignored her.

2 pm came and nothing happened. Nothing happened for a really long time. Then at 3 pm the weather instantly cleared up and it was the most beautiful sunny day you had ever seen. Everyone just went home. I was really pissed, because I was now a ghost for no reason.

I was with my first love for 7 years, we were basically kids. We stopped dating 3 years ago and I met the man I am with now 2 years ago. The man I am with now just purposed to me and wants to marry me.. I still talk to my ex from time to time just to see how hes doing and we cut off the conversation but he always keeps in touch. Last night I had a dream that me and my fiance moved into a big huge penthouse and my ex showed up to my window with a letter and I took the letter and my fiance kicked him out. I began to read the letter and I couldnt fully read it because I was hiding in my closet so nobody can see me, but most of it was a letter he wrote to me asking for forgiveness and how he regrets what happend to us and truly is in love with me. The dream then jumps forward to me and my fiance in this new house still and its such a luxury home and thats not the life we live right now. In this dream the new penthouse still made me unhappy. I was overall unhappy with the house and everything my fiance was buying for me. I had the biggest closet in this dream with all the expensive name brands and I was still unhappy. The dream jumps forward again and my ex comes back and I let him in the house while my fiance is sleeping because I wanted to know what the heck he wanted.. then I woke up

A couple of years ago, I had a dreamt about a guy a bit taller than me, roughly 400lbs, super nerdy, with curly blond hair and glasses. We were at our wedding ceremony, and when it was my moment to say I do, I left him at the altar.

Flash forward a year after having the dream, I met a man with the exact same description and the same name as the man in the dream. We dated for a few months, but he was a total POS, so I left him.

Context: this dream revolves around me a baby and a ex female friend. Me and her aren't friends after an argument. But keep her in mind.

Dream: I am napping in my bed and I hear some crying, but I ignore it. The crying increases and I look beside me and it's a baby girl (blonde hair, and brown eyes) and I grab the baby and carry her until she goes to sleep (surprisingly in the dream I didn't react until in the morning). The next morning I show the baby to my mom and I don't remember her response, later on I found out where my friend lived (let's name her J) and I knock on her door, she answers. And I remember I got super emotional and hugged her really tight, I hugged her and told her "thank you" the baby had her hair and both of our eyes (brown colored)

What does this dream mean? I can't find anything that is close to the situation I had in this dream. Me and a ex best Friend had a baby and had our eyes and her hair.
