Recently I've been smelling things that remind me of my childhood, like maybe the smell of the laundry detergent my classmate used or the smell of a certain classroom. It's happening so frequently I'm starting to think that I'm dying because instead of seeing my life flash before my eyes I start smelling these nostalgic things slowly until I die. I'm not even sure if it's all a coincidence, or if the source of the smell exists, or if I'm hallucinating them.
