I dom’t usually notice the sense of smell in dreams but in May 29 - Final Fantasy Forest
“I can smell the lush greenery as we walk.”
last night I had a dream in which i recognized a relative who was coming into the room by the scent of her perfume. completely neutral, nonlucid dream. made me think of this topic 
im pretty sure i wouldnt be able to recognise her by scent in real life though
