What are seeing a dead partner dreams about?

I just had an awesome day with my boyfriend yesterday, like it was so much fun and we were together and so loving like we usually always are.

He got home safe, I ask him to text me every time he does so I know.

I went to sleep and just had a dream where him and I were hot air ballooning and doing stupid stuff and he fell out and I literally watched his body plummet and hit the ground. Then my dream blacked out only for me to be feeling an extremely heavy weight on my chest and I was crying. It got to where I had to tell my parents that my bf died and then I suddenly woke up.

It felt SO real and I was incredibly relieved that it was a dream but also felt the heavy weight of grief on my chest but I didn’t wake up crying, I just had such a strong emotional reaction to that dream and I still can feel it even an hour after jolting awake. What does this mean? I’m really really worried now.

I was staying the night at my dead grandparents house that I have not been to for 8 years. The house was sold in 2013 just after my grandad died in 2012.

I was in the living room of that house at night and I was sleeping on the floor in there with my brother. Suddenly my dad calls me or tells me some way that my grandad is back from the dead even though he has been dead since 2012 and his body is now ash.

After hearing this I see my dead grandad sitting in his favourite spot on the sofa it’s still dark but there is a slight glow coming through the windows from the moon light. My grandad seems to be sleeping or dead. He then wakes up and stands up he is a lot taller in this dream for some reason. He talks to me and laughs and says hallo. I then give him a hug because I missed him so much.

He then starts to act weird like crazy and not make sense he gets quite creepy. Random laughing and movements like he is possessed. He also changes to what he looked like when he was on his death bed really ill looking and skinny. Suddenly there is no light in the room it is now pitch black I get scared and run out of the house with my brother I run down the street at night and go into a random strangers house. I open the door and a blonde girl greats me she looks at my brother and smiles and says oh hi how are you?

In this dream apparently this girl was a friend of my brother from school. She invited us both in i then get out a phone and try to call 999 because of my dead grandad is acting crazy and scary. I can’t seem to get connected to a person on the phone so I sit down at the table to have dinner with the girl and her family.

I think more about my grandad and relies that he had been sitting dead on that sofa for a really long time then suddenly came back to life. The family at the table then screams and my grandad is in the house acting crazy and he is now rotting and falling apart. He breaks his leg and twists his foot round on purpose and laughs. I keep telling him to sit down and take it easy and for him to stop because I’m worried about him hurting himself. My dead grandmother my dead grandads wife who died before him also appears.

She tries to give me a hug but I back away because I’m worried because of what is happening with my grandad might be happing to her too.

I run out of the house and as I’m running down the rode a huge wide trailer comes down the road carrying 4 funreol cars with coffins on top. It almost hits me but I jump out of the way and miss.

The scene changes and I’m at a graveyard it is sunny and I’m looking at a freshly dug grave. I notice the grave had my name on it. The date of birth on the grave is wrong it says 1982 but I was born 1997. I not shore about the date of death on the grave I think I kept seeing it change from 2020 to 2045 and back and forth .

A voice then says the life of this person is over you can either wait for the new one or go back to your one I’m shore I chose to go back to my one.

This dream has got me worried as I suffer from bad anxiety I hope this isn’t a bad sign.

Dream interpretation

( A bit of background to the story.. )

My partner 33yo male and I 20yo female have been dating since I was 17 and in the past year everything has gone down hill..
I caught him cheating (via social media) but stayed out of love and hope that he’d learn from his mistake. During this time my best friends husband passed away suddenly so I had pushed my emotions aside to help her. (Still tried to juggle my relationship issues and mental health).
My partner admitted to having an addiction to cocaine and one night when I was with him I tried it.. I instantly became addicted and eventually this lead to myself having multiple seizures due to overdose.
My addiction was so strong (his too) that it felt impossible to stop. I moved away for a few months and came home clean. He told me that he was drug free also but when I got back he was doing coke again. (please do not jump to judge. Addiction is one of the worst battles there is.)
I ended up doing it again with him but I cut down drastically.

THE DREAM

His mother had a dream that she had walked into his house to find me having a seizure on the floor. She stated that it looked like I was about to die. Her son (my partner) was behind me standing and staring at me. He was (her words- The Devil.
He was standing and groaning and not talking. Smiling and staring.

I have a pretty well idea as to what it means but please opinions and interpretations are appreciated.

TL;DR at bottom.

So, last night I dreamt I was marrying my ex gf (Dawna. we broke up a couple months ago. Ended okay, then things turned to shit fast) anyways...
She was to get ready and do her thing for the day. I had my suit so all I needed was a lineup and taper from a barber. I was in the mall talking to my barber friends and it ended up taking too long. Eventually one of my old friends I went to barber school with asks my barber to go for a drive so we go. He pulls out cocaine bags and I'm like, fuck this I'm out. I open the door to get out and there's cops. So we book it on a high speed chase. I'm terrified thinking this is it, I'm done for. We toss the drugs then they slam the breaks in the middle of the strip in Vegas and I get transported into the crowd as the cops swarm the car... I'm scott free....
So then, I get dressed, my hair is somehow already cut, and I'm walking towards the venue drinking beer. I get there, stand at the alter waiting for Dawna to come down. She looks beautiful, walls down, we say our vows and then I lift the veil, then *BAM*, it's not her... It's my wife!! (Jessica. She passed away a few years ago). So now I'm like wtf and not even freaked anymore. I forget about Dawna all together and now it's just Jessica and I. Living our lives with our 3 kids. Happy as can be. Only we have a newborn this time too.. and everything was perfect. We were shopping and hugging and kissing.
I felt like she was truly back in my life and everything was perfect. It was so intense it's the only dream I have ever remembered. It felt real. Jessi felt real. Her hugs were so realistic I felt it when I woke up..
Idk, just asking if anyone knows wtf it could mean.

TL;DR:
Marrying my ex gf. After some crazy trouble on my own, we end up at alter that day. I lift the veil and it's my deceased wife. And we have a newborn and live happily.

A couple nights ago I had a dream and my spouse who passed away was in it. It was awesome seeing him again. The weird thing about my dream though is that when we kissed I felt my dream self get pulled back and I jolted awake. My body kinda flung itself across the bed and it kinda hurt. It freaked me out. I don’t even know the right words to explain it. But it was weird
