What does the smell of burned toast mean?

Answer 1

Smelling burnt toast (when there's no actual bread burning) is called an olfactory hallucination.

It is possible to experience olfactory hallucinations when you have a brain abnormality, such as a brain tumor, or if you are about to experience a seizure or a stroke. In order to rule out these issues, you can visit a doctor and get a brain MRI.

Answer 2

Answer 3
