I have another weird one!
I was searching for a certain Green Day interview on YouTube or Google Videos or something because I remembered it being a good one, but I still didn't have it on my computer yet. The Green Day boys were sitting on a couch with Billie on the right (his right), Tré in the middle, and Mike on Tré's left. They all looked like they did in the American Idiot era, but Billie had longer and fluffier hair like he had for awhile later on the AI tour. I don't remember what the interview was about, but I really liked it and it was in 5 parts so I downloaded them all. All of a sudden I was in the world of the interview - it wasn't just a video anymore - but the couch was now outside in the middle of what seemed to be a university's main walkway. There were strange creatures all over the place that were walking around and climbing the sides of the brick buildings and stuff. They were big wolf sized reptilian creatures with lizard-ish bodies, but longer necks and legs than normal lizards and very snake-like heads with huge, sharp teeth in their mouths. They could also run surprisingly fast, almost like a gallop, and started coming to investigate the Green Day trio. As the creatures approached, Billie suddenly jumped behind the couch and turned into one of the them. He started hissing and making weird, eerie screechy growling noises (that sounded kind of like the Ring Wraiths in the Lord of the Rings movies) at the others and showing the long, razor sharp teeth and forked tongue he now had. Presumably he was trying to defend Mike, Tré, and the couch from the other creatures. It seemed to be working because he was putting on a terrifying display of ferocity that would freak out anyone in their right mind. The other reptile things were scared off and ran away, then Billie turned back into his normal self.
So apparently Dream Billie can shape shift now I guess!
