I have had quite a few of the "Hey, we need you to help out with the Muppets/Fraggles"-type dreams (with Jim usually the one telling me about the Muppets and Richard Hunt telling me about the Fraggles, since he knows I like Red so much).
I worked at a zoo a couple of years ago and got promoted to manager. I had a dream preceding a special event that Jim was at this special event as one of the celebrity guests. I offered him some food and such, and told him how much I enjoyed seeing him there ... and he told me, "You are the stupidest person on the planet." Now, I was naturally upset by what he told me, because I knew he was criticizing my job choice, since I've told him (in dreams) on multiple occasions how into The Dream I am. I asked him what he thought I should do since he's so smart (God, would I ever be that irritable to my role model?). He told me he'd tell me tomorrow (remember this phrase). I woke up and THAT MORNING I looked at the newspaper and there was a political cartoon about education with a drawing of a kid with a KERMIT backpack. Well, THAT freaked me out. LOL. I shook my head and told Jim in my thoughts that, well, I've been there and done that and it was a nightmare and that normally I would kiss the ground he walked on but I had to disagree with him on that one.
I've also had a dream about some heavenly trial where I've been nasty to someone and the judge for the trial is ... Mr. Hooper.
I've also dreamt that I was stuck in an elevator with Red and we shrugged and sang the Friendship Song to pass the time (I think that was when I finally saw Marooned on DVD).
EDIT: I also have had a few dreams about meeting either the Sinclairs, getting a job at WeSaySo, or meeting Spike.
