As always Mikey will answer in due course but from what I understand the objects you've mentioned are communal 'over there' also, much as they are here. Similarly there are communal landscapes, buildings etc. and we may also create (by the power of thought) for ourselves locally the conditions we like to enjoy - when we've learned (or remembered) how. Even here we create for ourselves local conditions we enjoy such as in our homes and gardens. I suppose if we had made sufficient spiritual progression we might be able to create larger objects and landscapes etc. in the etheric dimensions ourselves but I doubt we'd be able to hold them in perpetual existence by ourselves. None of that makes the so-called afterlife something that's not objective. It does exist for all even if different individuals experience different facets - little different from our own dimension of existence.
