I keep smelling fire, or wires burning when no one else around me does. why is this happening? just recently started about 2 months ago and usually occurs between 2am to 5am.

This : This may be related to a sleep state - an olfactory hallucination either while dreaming or upon waking up. I recommend that you see your doctor. He or she may recommend that you have a polysomnogram (sleep study) to capture the electrical activity of your brain waves as it is occuring; or might consult with a neurologist. Either way, it should be evaluated. Take care.
