All 3 of the stuffed animals that don't leave my bed all have their own distinct voice and personalities. I sometimes have conversations with them (just not out loud).

Gavin, my stuffed turtle pillow has the personality of a chill middle aged man who's proud of his son since he's been with me since I was maybe 4-5 and has dealt with a lot of my bullshit. He loves when I rub his shell.

Jake, my polar bear I got from a hospital when I was maybe 12, is a pretty happy and optimistic man with a voice that is a little high pitched and scratchy. He loves wearing his little bandana I fashion around him like a neckerchief and his little when it's spring or summer.

Laura, my stuffed brown rabbit I got maybe a year and a half ago, is a female with a voice like Tsumugi from Danganronpa V3. She's Jake's slightly older sister. I like to cuddle her because she's the softest of all 3 and because she's the easiest to cuddle with. She's my little dress up bunny, despite the fact she only has one outfit. It took some time, but she eventually got used to her outfit.

Edit:

Nobody probably thought this, but I totally looked this over and my autistic brain totally thought the part about Gavin made it sound like my actual dad isn't proud of me, which is false.

Also, I don't know anyone else in their mid-20s who does this.
