When I set the viewport shading to interior, the reflections in the bowling ball matched the room that I’m sitting in. That creeped me out

Lucky you!
but it is fun.
The only thing odd I find about it is, the reflection is not of a bowling alley. That said, however, it’s a damn nice reflection of a room. Sometimes I’d like to get such nice reflections.
