I'm currently in the process of writing a novella length story that does not have a defined plot. It has an overall man Vs. self(suicide related), but aside from that it is a plot-less drug bender through Europe. I am used to writing high fantasy so I've always got a very defined start middle and end. What I'm wondering is; In a man vs. self story (so long as each encounter gives the character some new learning) can they be pretty much random, and not tied together at all. Or does there really need to be a main plot line that runs throughout? Also, I haven't read many books I would consider man vs. self (Lights out in wonderland being the only one I can think of and that has a very good and linear plot), so any recommendations would be great.
