how do I know if my room stinks?

so like, i love how my room smells. it smells warm to me. like sleep. but maybe that’s a bad smell? i can’t tell if it’s a good or bad smell. to me it smells like cupcakes but i think i’m biased. my cat is always in my bed and i love how he smells. i dunno maybe i’m gross but this seems subjective and objective at the same time. how on earth can i figure out if my room actually stinks bad or if it smells good?? aughhhhh
