If it's a white wall, the easiest fix is to just grab some white-drying filler, fill the holes, and leave it at that. It'll be nearly invisible - your eye won't catch it the way it does a dark hole.

The filler shrinks as it dries, so you'll need to layer it over a few days until it sits flat when dry. Done right - and without overdoing it - you won't even need to sand.

For non-white walls, same deal - just paint over it afterward. Note that matching the existing color perfectly is nearly impossible. For good results, you usually need to paint the entire wall.

I’ve caused all sorts of destruction while moving furniture. My guess is, someone was moving a heavy bed made of steel. A hand slipped, the bed roller in an unexpected way and crashed into the wall.
