Searching people

Hi there you crazed oneironauts, I recently noticed something recurring in my dreams that I'd like to hear some opinions on.

I often find myself searching someone (no pun intended), sometimes over an extended length of time. It's not always the same person, it's different people but usually people I'm somewhat close to, good friends mostly and mostly girls.
I spend a long time searching for them in different environments, while doing other things that are mostly mundane stuff like talking to people and buying cigarettes or something.
I always find them eventually, but here comes the catch: as soon as I find them I either
A. Forget what I needed them for and why I was searching them
B. Realize that there was no reason for me to search them in the first place

While I'm actively searching I don't spend time thinking about what I actually want from that person, and when I find them I realize that it's nothing or that I've forgotten it. The search is usually not really urgent, but it's got a feeling to it like it would be pretty bad if I didn't find that person.
Any thoughts on this?
