I am CONVINCED i can smell carbon dioxide. no one believes me because it's an "odourless gas" but then what am i smelling. it smells different from my sweat or any odors. it's a sweet, kind of cloying smell that makes my head hurt, and i always get it when i shut the windows in my room for too long or sit in a locked car. it doesn't come from anything else i've checked so now i have this power and it's not weird enough to be important but i need to tell everyone
