If you repeatedly smell burning when nothing is on fire, you are likely experiencing phantosmia (an olfactory hallucination) or parosmia (a distorted sense of smell). This is relatively common and usually stems from one of several conditions.
Smelling something burning (like burnt toast) when nothing is actually there is a widely circulated stroke myth. Phantom smells are usually linked to sinus issues, nasal polyps, COVID-19, or certain medications. Occasionally, they are a symptom of a neurological condition like a seizure or migraine, but rarely a stroke.
Smelling burning when nothing is actually on fire is medically known as phantosmia (an olfactory hallucination). It typically means your brain's smell pathways or the nerves in your nose are temporarily misfiring.
Phantosmia is a condition that causes you to detect smells that aren't actually in your environment. It can happen in one nostril or both — and the odors may be foul or pleasant. Common causes include colds, allergies, nasal polyps and dental issues.
These olfactory hallucinations are known, medically, as Phantosmia. Some common smells experienced are burnt toast, chemical, metallic, cigarettes, burning rubber or on the sweet side there is vanilla, roses, lavender. This may happen as a result of a migraine, allergy, long Covid or a sinus infection.
Smelling smoke or a burning odor when nothing is actually there is medically known as phantosmia (olfactory hallucination). It is commonly linked to sinus infections, head trauma, COVID-19, or temporal lobe seizures.
Septic smells are predominantly characterized by a strong odor of rotten eggs or sulfur. This is caused by hydrogen sulfide gas, which is produced when organic waste breaks down in low-oxygen environments like a septic tank. It may also carry a musty, swampy, or raw sewage scent.

Yes, phantom smells (known as phantosmia) can be a symptom of a brain tumor, though they are very rare.
Distorted smells (parosmia)
Instead of smelling things normally, people might find certain smells unpleasant. Many describe the changed smell after COVID as burnt, chemical, rotten or sickly sweet. “This happens because healing nerves send incomplete signals to the brain,” Dr. Assar said.
Causes of phantom smells can include problems with the nose, brain, or nervous system. It's important to note that phantosmia can also be caused by psychological factors, such as stress, anxiety, and obsessive-compulsive disorder (OCD)—though these cases are less common.
In the paranormal community, ghost sightings are frequently reported alongside distinct "phantom scents," with tobacco being one of the most common. If you smell smoke out of nowhere, here is how the experience usually breaks down:
A sudden burning smell before a seizure is a common type of "aura" (focal aware seizure). This sensation happens when abnormal electrical activity misfires in the brain's olfactory cortex or temporal lobe, creating a phantom smell like burning rubber, smoke, or burnt toast.
Warning signs before a stroke often appear as "mini-strokes" (Transient Ischemic Attacks, or TIAs). These temporary blockages cause stroke-like symptoms that usually resolve within minutes or hours but act as major red flags that a larger stroke may happen within days.
Most people with phantosmia report it as an intermittent smell of something burnt, foul or unpleasant. Cigarette smoke and petrol are common but olfactory experiences can be varied. Sometimes it can be persistent.
A mini stroke, or Transient Ischemic Attack (TIA), is a temporary blockage of blood flow to the brain. Symptoms are sudden and mimic a full stroke. The five key warning signs can be easily remembered using the B.E. F.A.S.T. acronym:
Symptoms vary depending on the brain tumor's location
Yes, phantosmia (smelling things that aren't there) frequently resolves on its own. For mild cases triggered by a cold, sinus infection, or a respiratory virus, it often clears up in a few weeks or months as the underlying illness heals.
The most common initial signs of a brain tumor are persistent, unusually severe headaches (especially those that wake you up in the morning) and new, unexplained seizures. Symptoms vary greatly depending on the tumor's size, growth rate, and exact location in the brain.
An olfactory hallucination, known as phantosmia, makes you detect smells that aren't in your environment. The odors you notice in phantosmia are different from person to person and may be foul or pleasant. You may notice the smells in one or both nostrils.
Phantosmia—the perception of a phantom odor that isn't actually there—is a known, reversible side effect for several common medications. The most frequent culprits include antibiotics, antidepressants, chemotherapy drugs, and certain blood pressure or cholesterol medications.
Experiencing a burning smell no one else notices is medically known as phantosmia (an olfactory hallucination). It can be triggered by nasal/sinus issues, viral infections (like COVID-19), head trauma, or neurological conditions.
[4,5] In the case of low levels of exposure (0.05 ppm), early signs and symptoms include the smell of rotten eggs, fatigue, headaches, nausea or vomiting, dizziness or lightheadedness, and poor memory and concentration.
The characteristic "old age smell" is scientifically known as nonenal (or 2-nonenal). It is a chemical compound produced when the skin's natural oils and fatty acids break down and oxidize as we age.
A full septic tank typically shows warning signs like slow drains, gurgling pipes, foul sewer odors, pooling water in your yard, or actual sewage backups in your lowest fixtures.
