Structure of dreams

I have had a lot of dreams recently where I am performing some task that never seems to be complete. It's like there is a mission or a purpose, or an action that I am doing, which would ordinarily be completed quickly, but it seems to go on and on for a long time.

For example, I had one dream where I lost a bag and kept searching for it, but I never seemed to find it. In another one, I was cleaning up a room and picking up my belongings like a wallet and other things that had been in my pockets. In another dream, I was working on a boat and I was cranking on pulley of some sort.

Is this a common structure of dreams, and, if so, does anyone have any ideas as to what it means or why it comes up?

Sometimes I have dreams like that, too. What happens in dreams is often about your expectations, so if you have a rather low self-esteem or are afraid to fail in such situations, the dream most likely will turn out the way you'd personally, or subconsciously, expect the situation to turn out.

Anyone correct me if this is nonsense, please!

I had a recurring dream. Telephone wires. They would get in my way, and no matter how I tried to climb over them, I could not. I finnally figured it out. Telephone lines are lines of communication. When I realized that, I followed them and came to an understanding. I learned that dreams themselves are a form of communication. The mind does not communicate with the mind. That is a self-referential fallacy. It was an idea that for me was originally impossible to deal with.
