dream lover

i've been thinking about this concept for a few years.
it's not new.
millions of people have thought about it.
but i do wonder.
do i behave based on dreams i have but don't remember?
does my subconscious react to life
based on experiences and memories my conscious does not remember?

i'm pretty sure i do.
i know that dreams i do remember effect my feelings.

another quandary:
which is correct?
effect
affect
