What was the best dream of the past ten years?

Before it gets outdated, it happened in November 2004.
I was at a friend's house (of a friend I have never heard of) and we wanted to go to the bathroom. When we opened the bathroom door, the bathroom was replaced with... a kindergarten?!
That was weird. We ran down the stairs and we were forced to do activities or something like that. There was one saving grace in the kindergarten: there was an illegal sewer, with lime green water. We entered it, and we were inside a stinky place, with a slightly lowered ceiling. Once we entered a "sub-room", there were three tubes, two of them always went to wrong places. The middle tube worked, and we were stuck for brief seconds, before slime "geisered" onto us. And the girl that was with us said (and I remember clearly): "TIME SQUADRANTS! I NEED TIME SQUADRANTS!!!"
And then, the watery-slimey-geisery thing fell onto us, and we returned home from the ceiling. When we opened the door, the bathroom was back.
And I had jolly good fun.
