Odd brain associations?

Question

Does your brain ever associate a smell or sound with something that has absolutely nothing to do with it? Personally, whenever I open a bottle of Pepsi Lite, my brain automatically associates part of the smell with pencil shavings. I'm thinking that maybe my brain is associating the both because I used to drink Pepsi when I was drawing. But it's always Pepsi Lite, and I've only started drinking that within the last year - I also haven't drawn in about 2 years.

Answer 1

there might be a subset of the Pepsi Lite smell that matches the pencil shavings smell.
