Dreams have spritual representation in many cultures. I have had dreams that have came true. I don't have them any more. But don't remember them till it starts to happen then i remember the whole dream. all my dreams where from when i was a kid. when they start come true i can change the event in my now adult life. Some cost me to keep my freedom. Other save my life. Dreams are you subconscious entering your conscious mind. Take head to your mind at rest. While you sleep you mind is wide awake processing all you said did saw and read. when tramitic things happen your mind saves information that could damage your mental suitability and suppress them out of your memory. sometimes it relinquishes the information in the form of dreams. Your dreams are put together with reason. your brain makes faces you never saw colors that don't exist. It choses things that you know and don't know. safe guard your dream some has even made a dream log and wake up when they have one and record it because we forget them.
i use to have trouble with extreme horrific nightmares. being attached having monsters hunting me so horrific it my brother would tell me it looked like i was fight the sheets in my bed. I would wake up with my bed soaked with sweat. I would have dreams the dead was after me.
Latter in college i learned it was all do to my child hood i was molested, beaten, verbally abused and exposed to things things no child should have to endure.
Latter i thought my self to notice when i was dreaming and i would summon a sward so sharp and powerful if could cut threw any thing that drove to hurt me. I don't have night mares any more. I know when I'm dreaming and can make my dreams do any thing i want to do. Now when i have night mares and dreams i make stuff so funny i wake up laughing.
