Sensing the smell of someone who isn't there.

[Isisd]

It happens to me frequently. I don't imagine the smell, it's like it "appears" out of nowhere, and it's so real that I need to look if the person is around me, realizing right after that this person lives far away or can't possibly be there with me. I'm not referring to a specific perfume or artificial fragrance, I smell the odor of the person, that specific odor that anyone has and it's different for each other. Also, it happened to me with few different persons, that are dear to me (my grandma, my girlfriend...)
I wonder what it could possibly mean or if it could have a deeper meaning than what I think.

Smell has a lot to do with the way memory works.

Specific smell's are intricately tied to and associated with specific memories, which are oft attached to specific people.

One can easily trigger thoughts of the other. It could just mean they're on your mind subconsciously.
