Our dreams reflect what happen in our life every day. I think dreams show the deepest emotions and thoughts, which we often hide consciously from ourselves, so they refer to our fears and banned desires, consequently they are connected with our future. It happenes some dream can come true, because we aim subconsciously to do this.
I have rarely remembered my dreams recently. In my mind it is because my subconscious is intoxicated by excess of learning. My last dream was about physics and maths. It was strange. I had to solve the riddle associated with this subjects. The last I remember are the huge tree and gouges in the ground.
I have never had a prophetic dream, but sometimes I have "deja vu" and then I wonder if I dream about it. I don't cross out the thought dreams can help us to predict the future, but I don't believe in it in all.
