Phantom smells, anyone?

Wondering if anyone has been smelling things that aren't there. Since last night I've been smelling, wait for it...cat pee. Dreaming cat pee and I don't even own a cat. I've been doing laundry for 6 hours trying to rid my nose of cat pee but of course it's not working. I get the whole smell sensitivity that comes with pregnancy but have never heard of phantom smells. Luckily I didn't have this with my first pregnancy. I must have been a real b*tch in a past life...
