It might be. But it's probably associated with all kinds of things. Like, hallucinogenic drug ingestion. Temporal lobe seizures. Alzheimer's. Alcohol toxicity. Food poisoning. Brain chemistry issues. And so on and so forth.
And sometimes, some people simply notice a smell that isn't there. Just like when you get an itch on your leg, but there's nothing there to make it itch. Or when you think you see a shadow at the edge of your vision and when you turn to see what it was, it wasn't anything at all. Or when you hear a sound that goes away as soon as you noticed hearing it.
These are sensory hallucinations, and it's mostly just the nerve endings doing what they do, and you happen to have honed in on them at that particular moment and your brain didn't get a chance to accurately interpret them.
WHY this happens - it can be a "disorder" or "medical issue." Or it can be random. I've had it since I was a little girl. I'd wake up on days when the ozone was thick in the air and smell cotton candy. Or mid-afternoon "bacon" smells. On my cotton candy days, the looking up toward the sun for the first time that day makes me sneeze. That's not a disorder either. It's just an automatic response and apparently many other people have it, but never noticed there was a pattern to it.
You notice a LOT when you have ADD
