Today I received my first small set of materials for experimenting a bit with perfumes. Once I opened up and smelled the Norlimbanol on a paper strip I realized I had "smelled" that exact smell before (except I haven't really). It is spot on the exact smell I experience if I stand up too fast and my eyes blacken a little bit (though this happens very rarely and only lasts a second or two). I however always just thought that the smell was the neurons was misfiring because of the low blood pressure and it was a nonsensical smell that didn't really exist anywhere else - until now.

Anyone else having experienced some imaginary smell (without smelling it) and then later realizing the smell existed as some sort of basic perfumery ingredient?
