Hi, welcome to the ehealth forum and I am glad to help you.
You seem to be perturbed by the sense of burning rubber and deja vu regularly.
There are a few causes for phantosmia(the perception of an odour when there is none also known as olfactory hallucinations), but one of the most common and well-documented involves brain injury or seizures in the temporal lobe. Those with lesions in the temporal lobe, often brought about by a stroke or from trauma to the head, also experience these olfactory hallucinations. Other leading causes of phantosmia include neurological disorders such as schizophrenia and Alzheimer’s disease. Phantosmia can also be attributed to overactive olfactory receptor neurons (ORNs) or the loss of inhibitory neurons brought on by a sinus infection or some other type of cold.
There does not seem to be any special association between déjà vu(familiarity with unfamiliar situations) and schizophrenia or other psychiatric conditions. The strongest pathological association of déjà vu is with temporal lobe epilepsy. This correlation has led some researchers to speculate that the experience of déjà vu is possibly a neurological anomaly related to improper electrical discharge in the brain. As most people suffer a mild (i.e. non-pathological) epileptic episode regularly (e.g. a hypnagogic jerk, the sudden "jolt" that frequently, but not always, occurs just prior to falling asleep), it is conjectured that a similar (mild) neurological aberration occurs in the experience of déjà vu, resulting in an erroneous sensation of memory.
You must consult a neurologist for thorough evaluation of your case and definitive diagnosis as the same cannot be made online.
Hope this helps. Take care.
