Without wanting to diregard what the other posts here say (I'm sure some people have intuitive dreams) I still believe that you have probably thought and read about parasites so much that your mind is working through it now. I have had dreams about the most bizarre parasites but I know its because once you read and face the subject you are also imagening it. Just reading how a worm looks you paint a mental picture. Now most of us do not really like the thought of parasites and the thought of having them is pretty gross. So this combination makes you prone to dreaming about everything you can imagine. i dont think it means you have them. Its really easy to get into this kind of panic regarding parasites and everything all of the sudden points out that you have them. Keep cool - if you are doing the cleans and keep an open mind to it, observe your body etc. you will be fine. Dont let your dreams drive you mad!
