Reminds me of mindfulness practices, having a word for it, and linking that word to a trip to the Maldives is likely what makes it so intensely memorable.
Very "intensely memorable" feelings/things don't have names!! The smell of old grass or barnes or rain on dry soil or kinds of breeze at certain temperature and level of humidity.. Many of these random things without names are still there and don't require words.
No one said they were required, just that words may help induce mindfulness of these sensations
Smell of rain on soil does have a name, though - petrichor.
And is a good example of "if you know the name, it makes the sensation stand out even more."
