Weird lighting/shadow when point light very close to surface

This is the ceiling of my room. There is a real-time point light, and it is located near the ceiling, because there should be a chandelier hanging off it. On point lights that are far from objects, this does not happen.

Can I get rid of this somehow?

The ceiling is white in color (and is part of a .blend imported model).

Never put a light too close to a surface. That’s the main rule. Also, keep the bias value a bit higher.
There isnt much else to do.
