I remember from my childhood dreams with a very intense smell. Those were usually nightmares: I would walk into the house and find it on fire, there would be a chemical fire at a nearby factory, etc. The smell of smoke was painful in those dreams. The chemical fire dream had a smell of ammonia in it, and at that age I didn’t know what ammonia was.
Last night, I had a fire nightmare again. This time it was an electric fire, and it smelled like a dusty computer, just much more intense. I also have a recurring fragment where the house smells, and I can’t figure out where it comes from.
In lucid dreams, I can smell and taste perfectly. I have had excellent orange juice, wine, tea…and one of my most intense rage dreams involved the smell of bacon.
