My Supernatural dream

I got caught up on the new Supernatural episode last night, which in turn fueled a weird dream.  Satan had taken over a warehouse and stationed himself in the center via spider webs.  As if that weren't creepy enough, he was surrounded by every kind of monster known to man and they were killing all the humans.  Someone cut a small piece of Satan's leg or pants off to make Sam meld into him (Sam was originally Satan's vessel) and something else happened to Dean, I can't remember.  Anyway, there was no one to save us from Satan.  There was a restaurant in the warehouse and Satan cast a spell over it to make it look normal.  A group of heroes (probably absorbed from my playing Diablo III last night as well) traveled to the warehouse to defeat Satan.  They knew how to kill all the various monsters and they did, but some of the monsters were kids.  There was a separate monster fight where I was fighting, too, but it was very disjointed and complicated; I don't remember much of it, other than it was husbands killing their new brides.  The heroes made it to the floor with the restaurant and they walked into the trap Satan had lain.  Most of them died.

Not sure what happened after that, but suddenly we were in a war and Crowley (the "king" of hell) was on our side (kinda like the episode I watched.)  People were out to kill him and I was sad because I liked him.  There was also some side business of my trying to find a new house to live in and then moving everything in and decorating.  I ended up at a hotel where we were all gathered to prepare for the war.  They caught Crowley, but I created a distraction so he could get away.

The next thing I know, we were headed to a cave where it was rumored Dean had been.  The cave floor was covered in wet sand and I found a digital camera half-buried.  There were pictures and videos of Dean, but he still didn't believe he had been there, because the rumor was he had run away with another man.  Somehow, this other man found out where Dean was and wanted to join him in the "alternate" world (I guess, TV world?)  His family from the real world was chasing him and he shot them with a grenade launcher.
