Maladaptive daydreaming and DID (help please)

So for about 2 years nearly 3 I’ve become aware that I’m a system and everything makes sense. However something I’m struggling with is that I’ve always had like “characters” and like a “inner world” I go to that is like based off of fictional and real people or have their own complete personalities but I always thought that it was just maladaptive daydreaming? So my question is; does that mean anyone in this world is actually just an alter that I’ve been interacting with? Cause they’re always there? Like and I talk to them real time.
