 Formally, the quantum state of an object which consists of \(N\) particles is defined in \(3N\) dimensional configuration space, see Albert 1996, 2015. However, in order to understand our experience, it is crucial to make a connection to \(3\) dimensional space, see Stoica 2019. We only experience objects defined in \(3D\)-space. The causes of our experience are interactions, and in nature there are only local interactions in three spatial dimensions. These interactions can be expressed as couplings to some macroscopic variables of the object described by quantum waves well localized in \(3D\)-space, which are in a product with the relative variables state of the object (like entangled electrons in atoms) and other parts of the object, see Vaidman 2019 (Sec. 5.6). Another way to bridge between the wave function of the object and our experience of that object is the three-dimensional picture of the density of the wave function of molecules of the macroscopic object which has the familiar geometrical form of the object. Note that in some other interpretations of quantum mechanics, similar densities are given additional ontological significance (Allori et al. 2014.)
