You say bedroom, home office and dining room. I say:

1. Play on a basic dreamcatcher theme, big long straight lines like a spiderweb crossing walls following the edges of your furniture or breaking them, and where lines connect into a junstion, paint a frame from them, like in a center of the web, and there put a drawing of thing you dream about, may it be from your past pr in your plans. Lines may be just a bit different from your wallpaper’s color so they aren’t too intimidating. Luminiscent paint works kinda great in the bedroom context, so you can paint some outlines with it.

2. Office space shouldn’t be too distracting, so maybe evenly spaced thin vertical panels may work. I don’t know what you are working on, but I suggest simple illustrations of this process, one picture at one panel, with a diagonal cut-offs on the top and on the bottom with them repeating on each side, like you are looking at a film.

3. Organic vegetational shapes, green-yellow-red color palette. I don’t know your tastes, but a powerful Broccoli Boi drawn like a Kool-Aid Man can be a center piece of such composition and a fun conversation piece when you’d invite someone to eat there.
