Ok, this dream was my first attempt at incubation.
My brother and i have always been pretty different, opposites even.
so i said to myself before i slept "how could i get along with my brother"

and i woke up with this dream:

I remember i was in my old house, like most of my dreams start, looking out the second story window. A blue trashed up car pulled up to my house... then the dream suddenly became my familys vacation spot on a freshwater lake. Although freshwater lakes are usually a dark blue, hardly transparent, this water was more tropical... then i noticed the whole area was tropical, not a lake anymore, but a tropical area near the ocean?
the water was highly transparent, a perfect example of tropical water, light blue and such. the dock area which i was at transformed, the gas pump area became a concrete platform going down in the water, possibly a boat ramp? so the next thing i remember is that i was in the water and sitting down with only my knees in and looking around the dock. This is what is strikingly strange... 2 motorcycles on another concrete platform, wheels partially in the water, completely stupid! I am not lucid yet, so i accepted this and kept sitting there. then the current came and started sucking me out into the open water! i grabbed onto part of the dock, if i let go, i would die, so i yelled for help. My brother came out and jumped into the water trying to get to me, but another strikingly strange thing happened : the current pushed him the other way. He could not get to me because it pushed him to shore. And my dream ends when i let go of the dock, and the current carried me back to the rest of the dock.

I know the reasons why the current carried him the other way, we are near opposite... but i do not understand the motorcycles nor the current carrying me back to safety.
