What are seeing a dead pet dreams about?

A month ago my dog died. I cry about him almost every night. After crying I eventually fell asleep. In this dream it felt way too real. For the whole dream I was just petting him over and over. He looked so happy and alive. In the back I saw three other dogs. Two of them were my current dogs and one of them was my old dog who passed away 10 years ago. I said “I just want to hold him again” then I woke up. The dream felt way too real. Is this some kind of sign that he’s in peace now?

So my cat passed away about a year ago. He was my best friend.
Last night I had a dream where I walked into a room and he was there. Just laying stretched out like he use to in a patch of sun. He lifted his head and looked at me. His tail waved a bit. I said his name. He meowed.
I got to pick him up. It felt so real. It was like I felt his weight in my arms. I buried my face in his head and cried. I told him I missed him so much. I woke up crying.
It just felt so real. I have no idea what it means. But I needed to see him so badly.
It's the first time in a really long time I've had a realistic dream that pulled emotions out.

So anyway what happened was I got my mom's car and I'm driving it around but because of dream logic it acts more as a teleporter. Anyway I ask my dad if he would like to go to the Musium, and he said no so I decided to go by myself but he is already there. He asked he if I wanted to go in and I say yes. Then after a bit the Musium closes and he gets locked inside, but I have conflicting feelings between saving him, or myself as the door would close if I went to save him. So then I did the stupid thing and went to save him but since he was locked behind a different door we couldn't get to eachother. Also now is a good time to mention as it was only mentioned around this point, that I am Tim Templeton from boss baby with a real life hampster. but back to the dream, I decide to go searching for other ways out and then I hear angry dog noises so I go investigate. It turns out it was a giant plastic looking, void coloured dog ,which was also headless but was just trying to play. But after a few seconds of watching it I decide to look for more exits, now this took a while so I will just skip it. So my hampster says something like "try that window," so I do and it works. So I get teh fuck out of there forgetting about my dad. And (because of dream logic) I am just in the sky on something like a bicycle mixed with the Wright flyer. Then my hampster is attached my two strings, one to the vehicle and one to the wings. Then the one attached to the wings break and because of gravity the hampster falls breaking the other string. And we are up really high in the sky so he falls to his death but all it does is decapitate his head and after a second I notice and go down. I go to the the hampster and say "oh no" and the hampster responds with alot of saying he doesn't want to die and stuff like that and then says "I don't want to die, oh well *fucking dies*. And then there is sort of a post credits screen with tim Templeton answering the questions and I'm the interviewer. Tom says "I think out of all of my pets, Maurice (the hampsters name) was the hardest to loose. Then i look behind him and there is a board with all of his dead pets names and some of them have the animals species in the background of the word. Anyway I skip a few and to the last one and it's the outline of a dog with a creepy ass smile and he has a little hair curl droop thing. So I say what about *I do a creepy ass smile?" And then Tim just screams while holding his head down and then screams "bbbbbuuuuuddddyyyyyy!"

I had a horrible nightmare about 3:45 am today. My 11-mo puppy Mochi had died. I’m not sure how but it was unexpected. In the dream my fiancé brought me back her cremains after driving her body out of town to get “aquamated,” a specific kind of cremation that they don’t even have around me.

When I got her back I couldn’t stop crying. Like I was full on sobbing on my living room floor. I felt so guilty because I always said “she’ll never grow up! She’ll be puppy forever!” Meaning I thought she would even act like a youthful puppy even as an adult. But I felt like I willed her to die.

But I was able to see her walking around everywhere. She could see me but not hear me and I couldn’t touch her. She kept begging for me to pet her but I couldn’t and she looks so confused and hurt as to why i wouldn’t love on her. My other dog was so depressed too.

In real life I’ve been crying for 45 minutes straight. She’s a very healthy little lady and now I’m just hugging her.

First of all I'm sorry if this doesn't belong to this subreddit but if it does well here's my expirience.

I had my fair shares of sleep paralysis etc. Pretty typical, can't move and a creepy demon stares at me. But this experience was way worse than a sleep paralysis.

Dreaming: I was casually shopping some new clothes on a fancy store, I had to walk yo the stairs but every step I took was heavier and heavier, Sudently everything except the stairs disappeared. The only thing on the stairs is me and my dog. At this point I was sure I was dreaming because a few days earlier our father found our dog dead in the hospital after he ate poison. I knew this couldn't be true so I shouted "This can't be true! my dog is dead! you're not my dog!" and a slender man jumps care effect blurred my eyes.

- I open my eyes on bed, thinking this horrible dream is over, I'm going to the kitchen to drink some water only to find my dog sleeping on the bed he used to sleep when he was alavie. He didn't move, he just stared at me. "This can't be true, but I woke up, just leave me alone! " I said. I was freaking out and I was beating my self to wake up only for the that same effect to blur my eyes once more.

-I "woke up" but I couldn't move. My pc screen started doing the effect only to see a face straight out of a horror movie staring at me, and talking to me in a language I couldn't understand.

-Second time that I "woke up" walked out of my room only to see my dark living room and a big figure staring at me

-Third time, roaming my dark house hearing scary noises. Decided to walk down my apartment to my grandmother's house only to repeat a dream I had 4 years ago, running from the living room under my grandmother's bed while this "thing" followed me, seeing its feet before I woke up.

-I'm finally awake, it's 6 in the morning and I walk out of my room. My dog's bed is empty but I still have a feeling I'm about to start all over again, thankfully hours passed and that's the moment I was convinced that I was not dreaming.

Some info's:The dream screwed me up really bad, having the fear of being trapped on a loop even though you're aware that this is a dream is really horrifying. I just have to expirience negative feelings and memory's of my beloved dog staring at me with his silly look until the loop breaks. But I won't be aware of that since I had to wait hours to be convinced that I escaped the loop. I haven't got trapped on this kind of loop since this incident and I'm truly thankful for, every time I have a sleep paralysis I pray that I will just wake up normally the next day.
