Lord of the Rings/ Harry Potter

Last night I dreamed I was starting a video game called Yoshi's story. I've never played this before and I'm watching the title sequence. It's all the multi-coloured yoshis running accross this huge brown field containing the tree from the kirby games. They are running from a giant dust storm which scatters them when it hits them. The title sequence ends and I get to choose my character. There are the usual characters like Mario and Luigi, but then there's also Aragorn, and then two who seem to be a mix between toad and a smurf. I want to be toadett/the girl smurf, but when I click on her she goes into a monologue about how Aragorn can't be king. Then I am Aragorn and Gandalf is here as well as Grima Wormtongue, who has come to our side. When Sauroman shows up Grima starts sobbing and saying how he wants to go back to black magic. I (as Aragorn) become very angry and attempt to stab him in the back between the ribs, to my dismay I can't harm him at all because Sauroman is protecting him. They do something to Gandalf, who is now Dumbledore. At once I'm myself again and I'm watching Harry sneak up to Hogwarts and tell Dumbledore that he has to come at once in order to save Dumbledore. (This made perfect sense in my dream, I swear.) Harry then throws a note off the wall of the castle which flies over the lake and is caught by Hedwig. My friend and I are watching this from a very large trampoline which is floating in the air. We watch Ron and Hermione climb the wall in ninja gear and meet up with Harry at the top. The three of them then jump off the wall into the lake. My friend and I talk about how we would never jump into a lake in England, and she says it gets to 32 degrees below 0 at her home there.
