I Woke Up To A Funny Smell This Morning ...

I woke up to a funny smell this morning ... kind of a chemical smell. I smell it everywhere in the house, especially in my pillow, but not outside in the brisk air. No one else in the house smells anything, in the house or in my pillow. I have tried subduing the "bad smell in my nose" with inscense and such but without luck. Is it my pillow? My body odor? All in my head? What can I do about this? The aroma is very off-putting!
