How to set up an indoor scene? Lighting is off: Example

I am trying to make an indoor scene. I am not sure what I am doing wrong, because the lighting is not working properly. I has large shadows, that are blocking the ground and walls. Is their a special way to make indoor scenes? How should I go about it? Is there a way to make light not shine on a certain area? Thanks!

Indoor scene means a roof/ceiling… But you can also just delete the directional light and skylight if you don’t want a roof/ceiling.
