Anyone else experiencing smell hallucinations?

That's a very common symptom of one type of epilepsy (no regular seizures just olfactory hallucinations), maybe consult a neurologist (I had that and anti epilepsy drugs mostly stopped it)

You just have very sensitive sense of smell, which is very commonly amongst people with bipolar disorder. You are high functioning!!! You can either ignore it! Or move to another city/state/region

Olfactory hallucinations are known to be CAUSED BY DEMONS , OR KARMA , OR DEATH. Try to keep your favorite potent essential oil with you at all times! 🪔 Frankensense oil , lavender oil , peppermint ..., eucalyptus , lemongrass , sweet almond , tea🌴tree , sandalwood , and so many others. It may be gastrointestinal. Buy licorice sticks (chew sticks made out of licorice root) , neem chew sticks (which I found on sale on ebay!) , etc. Chew on them and change the gases in your stomachs and digestive tracts with this to start the process of getting rid of this. Red meats all have worms naturally BUT ALSO BACTERIA (Which causes the oder you smell!!!). These are natural. If you're healthy they are not harmful. As well as dairy. So know where it's coming from!

Just a thought but wondering if what your smelling is negative or positive ions. I can smell negative ions more than ppl around me. An example of negative ion would be “smelling” rain fall. Not sure if that connects with what you’re smelling but could be something to look into and see. I would say overall I smell a lot of things others around me don’t but I’ve never thought of it as a hallucination.
