I can't but help to comment on this thread.
I find it fascinating that it is in fact bugs, fibers, or other Arthropoda-like objects which dominate the hallucinatory senses in the case of both delusional parasitosis and cleptoparasitosis. These are their clinical terms I'm using.
imo I don't think it's necessary to seek help unless the hallucinations are altering your life to a degree that it impacts your daily function to some significant degree. The likelihood is you'll be prescribed drugs that decrease neurotransmitter activity and have terrible side effects which you will not be able to voice to your doctor since your neurotransmitter activity has been inhibited. It's a terrible hell, but it's a reality few see.
I agree with a fellow dreamer with his words on pressing the unknown boundaries of reality. One must exhibit caution when doing so, however. The biblical statement of "seek and ye shall find" always applies.
I think it is important to note that no two people think alike, but I do believe two people can think exactly the same thing at exactly the same time. Documented cases of folie á deux are the evidence this is true.
Nevertheless, when we go accusing others of using drugs before we consider all possible realities, we bury this subject in human ignorance.
