Dream About Neglected Dog Mental Health Struggle

This dream takes place in my childhood friends house. The dream is that I have a dog who I am unable to take care of properly because my parents don’t care about it. It’s implied in the dream that the dog is very neglected. It’s also implied that the dog is aware and expresses sadness at being ignored. In the dream, I am trying to make an effort to reconnect with it but I feel like it’s too late and I am unable to. In the dream, the dog is able to change forms. One of the transformations is to an autistic or mentally disabled kid who is supposed to be my brother (although he doesn’t exist in real life.) For whatever reason, I make a post on social media venting about him and my art. I say that I am unable to finish my art because of him. My post is liked at first but then quickly becomes controversial. I end up deleting the post and try to double down on my argument despite feeling ashamed. I then vent to some kind of ai robot about him. It is overly emphasized by me that he is non verbal and I don’t know if he is going to be able to speak. My role changes from sibling to parent. His transformation changes again to the dog who for some reason, is very overweight now. The dream then switches to me playing a game I used to play in my childhood. The game revolves around collecting stuffed animals and then playing with them in a virtual world. In the game, I have gotten a new pet that has a tinier animal attached to it. For some reason, I am able to change the design of the animal. This animal which is a cat, then transforms into a horse. This horse appears to be similar to the dog. It is sad and neglected. I try to design the horse with military clothes as I had used those on it in the past. I then try riding the horse but it is either too small or too unwilling to ride. That is where the dream ends.
