Occasionally I will get a taste in my mouth and or smell a food that I have not eaten in a very long while, decades even!
No one around me is experiencing it so it’s not an aroma in the air but a definite taste and smell particular to me.
I suppose it could be a craving but it happens randomly with no rhyme or reason.
In the last few minutes I could taste Neapolitan ice cream which I probably haven’t eaten in thirty years!
