Dream Smells

In dreams, sight is often blurred, and sound is more often felt rather than actually heard. Touch and taste are almost non-existent. But smell... DAMN smell seems to strike at you full force.
My dream last night had me going down a walkway which seemed to be a cross between the area outside my high school's auditorium and some street in Cubao. For some reason, dog shit and other charnal material littered the concrete, and I swear I could SMELL it. It almost makes me want to take a shower immediately after I wake up (which I do, anyway). What was the dream about? Can't remember. But the smell stays, strangely enough. Weird.
