...................when "in twilight sleep", and are less common in full wakefulness, except in the elderly, who can develop hallucinations, and a whole range of "delusionary or aberrant" behavior. I have had L-dopa induced hallucinations of a generally "non-threatening (scary!) type for years, but when i was on agonists and/or narcotics, they were much , much worse. If one has never had these experiences they may think that they are losing their mind, but you aren't, it is just another bad side effect of "messin with your brain" that the medications are normally responsible for. A lot of people get auditory hallucinations which consist of "hearing voices" or other "sounds", usually just a bothersome acceptable side effect from meds, but frightening and scary at first. You will learn to differentiate between what is real and what is PD related. However if these events last more than a short time or with great frequency than an atypical antipsychotic, one that has low dopamine receptor antagonism, may help to alleviate them. Narcotics are particularly bad in working with l-dopa to produce hallucinations. Narcotics are in general contra-indicated in PD patients, so don't messs with them unless you are in a very bad way with pain.
