There's the whole argument that Stands themselves are the human psyche made into physical form through the mind's reaction with whatever was in the meteorite that makes up the Bow and Arrow. Because of that, they exist in another dimension that overlaps with our own, which explains why they phase through objects in some cases, or directly interact with them if they so desire or if that's how they operate.

Like I said, whatever was in that meteor had such extreme effects on the mind that it allowed it to generate a physical entity out of thin air. This ties into the whole "Stands are such bullshit", in that the imagination itself is not limited to just comprehending the laws of the universe, therefore explaining why Stands can bend said laws without needing complete explanation or comprehension to do so -- If the mind is capable of thinking unrealistic situations up, then Stands can make things virtually unrealistic as a result. DIO and AU Diego could stop time but they themselves couldn't phrase it properly or completely understand it anyway. They just needed to work within their ability and that's all they care about.

My Chemistry teacher said that the basis of Stands, and a majority of superpowers and abilities for that matter, are "Cause and Effect"; Stand does something, something happens. Araki just likes to have certain Stands feel more realistic with respect to scientific concepts, theories, and ideas, but sometimes falls short, and other times just throws reality out the window in order for a Stand to work (Stands like Death 13, Man in the Mirror, and Bohemian Rhapsody), hence why "Stands are such bullshit".
