I have heard that people with BP have heightened senses. My solfactory perceptions are odd, in that I can only pick up on some scents and not others. For some scents, I have heightened perception, whereas there are other scents that I will pick up on long after other people have, or not pick up on at all. But yes, I do have a strong memory of particular scents -- particularly those that I associate with my grandmother (who passed away 10 years ago). Roses, lavender, and sandalwood. Nothing soothes me like those scents.
