Having weird dreams?

[guitargirl0219]

I have been having some very weird dreams lately and have been wondering what they mean. Here is the one I had last night.
In the beginning of the dream I am in sort of this school. Many of my high school classmates are there and we are all seated four to a table. I do not know the teacher. We are there for a very long time and all the teacher does is play different songs, and then we have to name the artist. It seemed almost like we were being brainwashed. Some time later, I am with all of my classmates again in this building, as well as one of my high school teachers. We are trying to somehow sabotage the brainwashing teacher. First, we go into the class room, where the desks all have beverages on them. We only take soda cans off of the desk, as well as taking a dog in the room (a shi tzu). We are then running around the building, knowing we are in grave danger if we get caught. We hide in a room, and the dog is now a beagle (like my own dog). Some people are about to come in the room, they are not of danger to us as long as they don't find out who they are. They come in, along with many beagle puppies. They are looking for the dog we have, who is the mother of the puppies. We show them that we have the dog, but they say that it isn't the right one, as the one they want is a shi tzu. I explain that this is obviously the dog they want since the puppies are also beagles. Next thing I know I am on a street corner walking toward my house. In front of my house is an ice cream truck. In the dream, I know the woman who drives the ice cream truck, and she greets me an offers me some ice cream. I pick some sort of peanut butter cookie thing and enter my house. Then it is the next day and I call my mom. She asks me where I was the night before, saying she went to that school building to look for me at ten pm. I am confused by this because the night before I arrived home at around six. End of dream.
I have been having odd dreams all week all though they have not all been similar to this one. Most of them however, have contained:
-dogs (in one, my own dogs were talking to me)
-some sort of danger (in one I was kneeling down with three people and a man was going to shoot one of us in the head)
-high school
-some sort of misunderstanding between my mother and me
other info: I graduated high school one week ago.
Please help me figure out what these dreams mean!
