I don't know if there are common themes, reoccurring ones, to my dreams, as i generally don't remember them (unless after awakening i actively remember and repeat in words what i have dreamt), or if i do i don't interpret them.
One dream i often had was me sword-fighting with some woman (i do not remember her visually, just the feeling that she is a good looking woman, but mainly that she is kind and that i actually love her, at least my dream role does). I don't remember (in the dream and now for sure
) why we two are fighting but sometime i land a hit with my sword (nothing deadly but serious it always seems) and then i immediately turn from fighting her to try to save her and to care for and about her. Actually, once i do that, it feel more natural for both of us, than the fighting.
I am no psychologist but it always seems to me that the 'message' of this dream is, that fighting not the natural state, but caring and helping for another is. That actually is my own 'deep down' moral principle. I am a very helpful person and think that fighting (be it with weapons or with words; fighting for the sake of fighting at least, although strictly speaking i think every fighting) is destructive and not wrong.
One thing though i know for certain, and it is wuite useful
: I have a certain mechanism, which wroks like this. When i sleep and dream, and i have to go peeing, my dream shifts towards a nightmare. It continues this road, to worsen and worsen. Now, somewhere along this point, usually it expresses itself in the dream by a normal dream with increasingly wrong-going things in it, i become lucid if you will and know that i have to pee and then i can actively wake myself from the dream. It is quite strange, but i dream this dream, and suddenly i know that this is only a dream, and that it turned nasty to say i have to wake. Then i wake myself up, it is just a matter of will, i guess, and then i am awake and can go to the toilet. This is pretty cool, although sometimes it annoys me because it corrupted a nice dream
