Description:  According to Ron's description from his BBS Radio Show on June 7, 2010 (around the 11-12 minute mark):

Listen to the entire show (flash required):
The answer given below is not 100% correct; it is around 99.9% correct (Ron and the Lightship are still looking into orbs at the time of this show). Orbs are like little scouts that come from the master - mother - jellyfish. The orbs have little tentacles that connect with our thoughts in our cellular memory. Each of your cells contain memories of your thoughts from your entire lifetime. The orbs can read this memory and bring a complete motion picture in your dreams - for example - of the memory they read and they can change the memory. The orbs can also come into our thoughts and can connect with other orbs, which could be connected to other people causing those people to come into your life. The orbs then can communicate with each other through you and the people, which can bring harm to you and them. After having the Creation Lightship remove orbs from you, the orbs can give you a waste product as they are leaving. This occurs in the head area; the orbs that are connected throughout the rest of your body seem to be just retrieving energies. The orbs around your head can make you drowsy, tired, depressed, etc.. because they secrete their waste products into you which numbs out your consciousness. This is why you can be having a great day, and all of a sudden you hit this downer such as when you want to do something. It might be a result of the orbs controlling you and not wanting you to do something - a form of mind control. That is why we are planning to put up a whole lifetime clearing to get rid of the orbs and their waste products.
