I've had a few Muppet related dreams before.
Back in September 2016, I had one dream that had three parts, and the last part actually had to do with the Muppets. I don't remember all the details, but at one point, I was pulling Sweetums out of a sewer or hole of some sort, USING A FISHING POLE! I had to reel him in, but it was hard to, because he was so big! Then I was doing something else with the Muppets (I can't remember what), but I woke up afterwards.
And then in April 2017, I had another one where I got to meet some of the Muppets again. I didn't really do much with them, though. I can't remember exactly which Muppets were there, but I remember seeing Fozzie. I think we were having lunch outside at a park, and we sat a picnic table. I just said 'hi' to them, and that's it. I don't really remember anything else from that dream.
If I ever have any more Muppet dreams, I'll post them here.
