Dreams are Strange

So last night I was indulging in my sleeping habit when I had all sorts of craziness go running through my head.

The first dream was the cooler/longer/possibly weirder so I'll talk about it in a bit. The second dream was quite bizarre. It started with a bunch of young people in a classroom (I'd say in the 10-14 year old range, apparently I was also in that age range). I distracted the teacher by asking a question about something and then the rest of the kids threw something (I think it may have been pins) at the teacher, thus killing her somehow.

Apparently this was the signal for some big to the death battle to start between all the young people and the older people. Everyone in the dream seemed to be under 15 or over 40 and not so much with the getting along. I stumbled upon a mother and young daughter (like 4 year old) and they were refusing to battle. Fortunately I just advised them to get out of the area.
What makes this dream particularly memorable (aside from the oddly high level of violence) is that I've had this dream before. I cannot remember exactly when I had it as it was a long time ago (at least months, if not years, ago). I do not normally have recurring dreams so that was rather strange. It is even stranger when one considers the distance between dreams.
The other dream was cooler/weirder and much less violent. Somehow I ended up being transferred to some bizarre other world. This world was not a real world but an imaginary one created by a giant yellow bird (and no, it wasn't Big Bird. Think a canary or budgie or one of those smaller birds which are or can be yellow in color but much, much larger).

The world consisted of five floors which could be travelled between by use of an elevator. There were a number of other creatures populating the world as well. There were a few people, a couple dogs (one friendly, the other very evil and dangerous) as well as some random creatures I can no longer recall.

I ending up taking the elevator to the fourth floor (which is where the bird lived) along with some woman I met in the created world. We convinced him to teleport us to the real world as it was dangerous to stay in his world (he must of been dying or something as it came up that if he died the world would cease to exist).

We got to the 'real' world but we were still in danger. Because we had come from the created world we had a sizeable chance of dying within our first day or so back (I think it was around 25% though it was slightly higher for the imaginary person because they didn't really exist (you would think that would really impact the odds but apparently not)).

We felt weak when we got back but we were quite determined to stay awake and thus not die. After a while though we did fall asleep but apparently we didn't die as we woke up the next day still very much not dead. And then we went bungie jumping for some reason. Ah, dreams.
