Hearing things and smelling things that are not there

I have noticed recently that I hear music or something like it. I am alone and I can faintly hear what sounds like music playing, but there is nothing. It is so faint I cannot even make it out or recognize it. It's weird.

I have also been smelling things that either nobody else can smell or are not there. I woke up this morning because I smelt what I though was a skunk or maybe skunky weed. I went out to the living room and I could still smell. It was very strong wherever I went. But husband who was home from work and had been awake said that he smelled nothing. t really worried him because my reaction to the smell was clearly honest. The more awake I became the more the smell went away.

Phantom music and phantom skunk smell. Very odd.
