Smells like Something is Burning

Yesterday as I was driving down the interstate, during my commute home.  I suddenly smelled a very strong odor.  It was the smell of something electrical getting very hot - like it was burning.  This is a type of aura that I sometimes had in the past when I was getting close to having seizures.  That type of aura is known as an olfactory hallucination.  (It's a smell that isn't really there.)  The smell was very strong this time.  I was nervous.  I didn't know why I was experiencing this smell - I had been well-hydrated and had been sleeping well too.  

Then the radio quit working.  What a relief!  It wasn't just in my brain, it was actually something electrical getting very hot.  Brought back memories of seizures, but luckily, this was just the real smell.  I guess I'll have to get used to really smelling things now.
