Is it Possible to "Dream" about Odors?

I'm been "dreaming" about odors (i.e. rancid water, soy sauce, musk cologne, cleaning fluid, etc ) in my sleep. Is this possible? I never wear cologne, but I sometimes smell it when I'm sleeping, then I wake up and it gone. The other night, I smelt soy sauce in my dream. When I woke up, I looked around, but there was no soy sauce. Weird.
