When I was kid I loved the smell of gas.
Did the smell make you think of anything specific?
I dreamt to be a racecar driver.
It's nice that it reminded you of a fond dream, but you should be careful smelling gas. It's bad for you and your brain.
That's not related, mostly it made me think of how it could make you drive faster.
It's fine that it triggers a specific dream, but you should avoid smelling gas on purpose. While it has its benefits, it's bad for your health and it's important to keep yourself safe and well.
