Is it normal that i dream about interacting with animated characters?

I draw myself with fictional characters from various shows and games. Here are my top favorites.

Sonic the Werehog from Sonic Unleashed.

Lucario and Pangoro from Pokemon.

Brian Griffin from Family Guy.

Exile (Exilio) Mikhailovich Sandhusky from Road Rovers.

And soon I will be drawing Chance Furlong (T-Bone) from Swat Kats.

I draw myself with these characters as a coping mechanism and a way to vent from my emotional frustrations. Basically I've been lacking in physical affection since I was a child. I am 19 years old and soon to be 20 this July. My father abandoned me at the age of two years old so I suffer from abandonment issues, and my mother was always an abusive alcoholic that blamed all of her problems on me as a child up until I was 12 years old. I eventually got removed from my home and was placed in various group homes and other facilities. I was abused physically, sexually, emotionally, mentally, etcetera. I started to draw myself with my favorite characters because they were the only things, the only "people", that made me feel better, like a human being. I began drawing them around the time that I was in elementary school from the earliest time that I can remember, and still do to this day, as parental figures or guardians. I mainly draw them protecting me, hugging me, holding me, cuddling me, sleeping with me, or simply just holding hands with me or other simple acts of affection or physical nourishment. But, when I draw these things they're all drawn from the point of view and the state of mind of a 5 year old wanting the displays of fatherly love and affection that I have never experienced or received.

I later started experimenting with fan-fictions around the time I was in high school at the age of 15 as another coping skill and a way to vent with more intricate details with scenarios of myself being with a favorite character and addressing the problem with them feeling better afterwards. I'll add a touching moment or go do something really fun that I've either never experienced or something that I don't get to do often that I like a lot. But, considering all of these positives things. I have a lot of dreams, and even nightmares of these characters being portrayed in complete opposite ways of how I originally depict them in my drawings and stories.

In the dreams I have with these characters. It's from a third person point of view, everyone and everything is 2-Dimensional and vibrant and looks like an american cartoon and an anime at the same time but neither style is dominate over the other, it's an uncanny but intriguing concept of what my dreams look like as the quality looks as if it was ripped from a DVD. Anyways, I frequently have dreams of these characters not abusing me, but just being completely different than what I depict them as and having completely different situations. For example, Sonic is usually laid back and carefree and is all about having a good time. But, in my dreams when he's in his werehog form he's really quite and gets frustrated easily and when I try to comfort him or help him he gets more irritated and pushes me away when I try to do anything nice in general. I've only had a dream with Pokemon characters once. Basically Kemper, my Lucario, raped me in the middle of a battle with another trainer. With Brian, I've had a few that consist of Brian and I running from either police officers, criminals, or something bad is always happening to us but we're always together and working together but one of us always winds up getting severely injured or killed. With Exile from Road Rovers, he's usually really nice and affectionate, but in my dreams he's always angry and keeps his distance from me. He just looks as me with intense hate and disgust. He looks at me as if he means me harm. There have been few dreams where Exile has actually interacted with me and in all scenarios he is either avoiding me, yelling at me, pushing me around, threatening me, telling me the worst things that only I fear of hearing from people that I trust the most and only things that I would know, and there's been occasions where Exile has struck me.

Can anyone help me understand what the drastic contrast in these dreams mean?
