what to put on wall above bed?

i just feel the space is very empty. i know artwork would probably be the go to answer but any ideas other than that? idk i’ve never been into big art pieces in the house - i feel like it’s too much of a statement especially above the bed lol. if you know what i mean.

TIA for any suggestions! also i like a modern “clean” look. if that helps. so no like.. polaroid strings with lights lol. cute but not my style.
