Do you have the same level of imagination for all sensory modalities?

I don't.

I can imagine sounds so intensely that it has on at least one occasion become indistinguishable from real. I can also easily do this overriding of real sensation with imagination, with my sense of which way down is.

I can't imagine a smell at all, even though I can recognise them upon experience — if I want to decide which herb or spice to add when cooking, I need to open the container and sample some in order to decide.
