yeah, they are pretty big ideas, its true...That is why our mind neatly packages them in imagery. Every element of a dream means something, that is a very important thing to remember.
When it comes to finding an answer, it always concludes with whatever feels right. Dreams will help you identify feelings and then interact with them via dream imagery. And if that wasnt enough, we can even enter dreams consciously and interact lucidly with our subconscious world. cool stuff indeed...
