I don't think I mentioned this when I first introduced Angie and Rem, but how they interacted and became friends is a concept similar to Miss Kobayashi's Dragon Maid.

If it was an anime, there would be plenty of slice-of-life hijinks in the waking world, and magical adventures in the dream world.

Themes can include Magical Girl, Mecha, Medieval and Rem would secretly be a runaway princess or queen. Or something.
