First what is dream?
Dream is a series of thoughts, images, and sensations occurring in a person's mind during sleep. Did you know the interesting information about dreams that blind people also dreams, it just they don’t have pictures in their dream like we do. Their dreams are made of only sounds.
Second why do we dream?
Well, there isn’t really any direct answer to that. Scientists are still trying to find out more things about dreams and the cause and the effects. We know that the rear portion of our brain gets pretty active during REM(rapid eye movement) sleep, when most dreaming occurs. Some think that it's just the brain winding down for the night and that dreams are random and meaningless firings of the brain that we don't have when we're awake.
Some believes that you can dream about a particular thing. How is that? I will try to explain. Sometimes I dream of flying but not just flying like pan the lost boy. In my dreams I had wings with what I used to fly. Now this dreams just didn’t happen. They were the after effects of some of my thoughts. When I first saw the x-men movie I was obsessed with the power of the man with wings. I used to think about it all the day. How I could fly if I had wings like that. After a period of time this thoughts were permanently stated in my mind. And I could fly in my dream. I started having same kind of dream everyday. So this is how you can dream about a certain thing by thinking about them a lot.
If you say or think that you go to sleep and then you wake up, or directly you say that you don’t dream, that’s not possible. Scientists say that when a person sleeps he/she can dream 4 to 6 times in average. If you say you don’t dream that’s only because when you wake up you forget them. You might remember the dream you had before you awoke.
But it is possible to remember your dreams. By doing a few things. If you are one of those person who set up alarm to wake up in the morning then its really hard for you to remember your dream. We mostly remember the dream that we had before we wake up so you are dreaming and then suddenly your alarm goes of, then your mind won’t be able to hold the memories of your dream. Your brain will start focusing on how to deal with that horrible sound of your alarm instead of keeping the dream memories alive. So get rid of alarm clock if you want to remember the message of your subconscious mind.
Oh, yes. Some believes that dreams are some information that your subconscious mind is trying to tell you. Human brain is powerful enough to remember everything that you hear or see. But because we focus on certain things, we forget the other things that we think are unnecessary. So if there is something that slipped your mind and your subconscious part is trying to remember that then you will probably have dream or dreams related to that particular topic. So it might be important to remember your dreams.
I almost forgot to tell you the most interesting information about dreams. These special kind of dreams are called Lucid Dreams. Did this ever happen to you when you are dreaming and you know that you are in a dream and you are able to control what is going to happen? If yes, then lucky you. You are a lucid dreamer. This is really rare.
Now the last part of the title. Did this ever happen to you that you had a dream and similar things happened to you or someone in real life? Are you a psychic? I don’t think so. There is a 80% chance that it was a co-incidence and there is a 20% chance that your mind is powerful enough to create real life pattern. Let me explain. Let’s say one of your relative is sick but not enough sick to die. So you went to see him/her. As I said before your subconscious mind picks up everything you lay your eyes on and tries to inform you. Now your relative has some sign that a nearly dying man could have. You didn’t notice it that clearly but you subconscious mind did. So your mind made up a event with the pattern and showed you that through a dream. And a few days later your almost well relative dies. It was just an example and I hope this doesn’t happen.
There is something else. It is noticed that those people who remember their dreams are better in memorizing things than those people who don’t. so try to remember what you dreamt about tonight. This is a great exercise for the mind.
