Sometimes I see these short gnome-like characters that scurry away and disappear into nothingness once they notice I've spotted them. I only see them one at a time, and they never look at me, but I get the feeling that they know I see them. They're ugly little critters, only about a foot and a half tall, pudgy, and only vaguely look "human". Wonder if anyone here has seen similar looking "creatures"? Many thanks.

My dad sometimes "sees" people in the back yard , or someone on the couch or at the dinner table.. Usually the couch & dinner people he thinks are grandkids or someone he knows. The outside people he thinks are landscape workers.
Luckily nothing scary or troll like..

woW ! Could this disease be more insidious??

...................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.
