It's not that the average person can or can't smell the sames things you're describing, they usually can't, but that you can indicates a hypersenitivety with the olfacory senses. Your smeller.
It's not either good or bad. Some people have better sniffers than others. But usually it indicates some stimulating factor. I experienced quite a bit of that when I had all those bugs in me. As the bugs die off and the liver and adrenals get back to normal the hypersensitivety goes away. But I think a little bit of it stays with you the rest of your life. I can smell my wifes perfume from the outside barn.
But yeah, as you clean out you'll get specific sensativities. Smell, touch, hearing, vission. I liked when the vission got hyper. Everything was so sharp and crystal clear and the colors were more intense.
But, what you describe is not unusual at all. Just eat stuff you like the smell of. I can feel the oils the next day on my skin. Especially coconut and flaxseed.
Once the bugs are gone it goes away.
