expanding thoughts

I was thinking about this recently and came up with an interesting idea.

I could tell a story about a character that is stuck in a rut. Life with nowhere to go. Mundane to the max... you get the point. But suddenly, he is taken to another place, and as the story unfolds, he realizes another time, and in the body of another person. But when it happens... there should be another character that it happens to as well. Both characters chase each other though time. One believes that by killing the other they will return to a normal reality. the main character on the other hand is convinced that by completing specific tasks or quests he might make it back or understand better what is going on.

Each story will be random, each of the characters won't know when they are, or who each other is, what sex, what age, nothing. As each part of the story unfolds they find new adventures and have to adapt to their surroundings as well as try and figure out what in the time or space is going on?

I think I'm ready to start putting things together...
