Well I do have a theory based on something you said. You said you were out of the "good stuff" so that couldn't have been it! Well are you sure it wasn't being out of it that might be the cause of the wierd and bizzarre dream?? Someitmes when your body gets used to taking a chemical and it's withdrawn, it can take a few days for the body to have a form of withdrawl from it. You know, it takes time for the build up of a med to clear out of your system. You just never know though.
Not saying anything bad here though kiddo, just surmising what you said. I use Duragesic patches and I don't have any reaction until after I take off a patch. Then a day or two later, the place where the patch came off with sometimes welt and blister! So go figure, that shouldn't happen that many hours later but it does hahahahaha!
