I used to have the same kind of migraines. So much sharp smells everywhere, smell people across the street, things like that. Sadly headache didn't allow to enjoy that superability, even for normally pleasant smells.
It’s truly a horrible experience.
There is fantasy series “Mist Born” where one character has enhanced senses. All the pluses and minuses that goes with it.
Wouldn’t wish it on anyone. Well maybe perfume manufacturers.
For sense of smell. It’s truly amazing how much “detail” there is in every day scents. Can smell food and describe accurately the spices used. Also I can detect the tiniest amounts used from 20 feet away. Shocking people that are using it and don’t even smell it.
My personal favorite is a woody car smell Hanger in the car caused me to instantly be jealous. Not of anyone specific, but there is an intense primal feeling of someone after what’s mine.
Without migraine I don’t notice any of it.
