I'm going to list 3 possible reasons that is from my experiences in life.
1) It could be your home or the land it's sitting on.
We lived in a house where many times I could smell smoke. My husband and son couldn't smell the smokey scent until one particularly wet spring and then they both smelled it too. The dampness brought the burnt smell out of the walls.
Then one day, my husband happened to be talking with a plumber that had known the original owners. The plumber told him about 'Mr. Elmer' being an alcoholic and had set the house on fire once back in the 60's... We lived there in the mid 80's... So, burned smells to hang around when trapped inside walls and attics.
2) It could be electrical.
The few times that I have smelled the particular smell that you describe, it has been because a cord or an outlet has a short in it.
3) "Do you ever smell burning odors?" was one of the questions asked by my Mom's doctor when he ran tests on her and discovered she had a brain tumor.
Mom survived the surgery and lived into her elder years .
4) I would have given you a 4th possibility but Rhyknow done covered the paranormal possibility...

The above is an excellent post and mentions all the things I was about to mention save for one:
A few years ago I kept smelling a "cloth burning" smell over a period of a couple of weeks, but no one else in the family could smell it, even when it seemed very strong to me. My kids started teasingly saying I must have a brain tumour. The very real source of the smell was finally discovered, however, in the venting pipe in back of our dryer. Somehow a piece of popcicle stick got wedged in the elbow of the pipe, and dryer lint had become clogged around it causing the heat being exhausted to build up enough to ignite the stick and lint. It was slowly smoldering that entire time, and would have likely caused a bigger fire if we hadn't found it in time. I'm taken much more seriously now if I say I smell something burning.
