Is it normal for a taste of a food to remind you of a smell?

Occasionally when eating something it reminds me of something that I have previously smelled. Recently when eating a custard that had rose water in it, I had to stop after the first few bites because the taste reminded me of a strong perfume; it wasn't bad, just unappettizing. And whenever I take ibuprofen, the taste reminds me of the smell of garbage bags, so I obviously don't take them that often, even if I have a slight headache. Is this normal, or am I crazy?
