Can I do something I dreamed .....

So I do not see how you could control what you dream about. And anyway, if you dream of the future, not the normal white one knows that one of her dreams. Only when that happens in a dream really reminds you look back at the dream.

what in the world of everything and something for something? But your question is already clear. only can dream can not control unfortunately. are clearly experiences (good, as bad), as well as fears and hopes are often processed into dream. But when, in what intensity, and if at all, you do not know before.

There are many people who think you could read the future with dreams, but that is scientifically highly controversial and is viewed as highly unlikely, just as commuting, reading maps or such nonsense. From your past you can dream, if you for instance, very hard to think. If you look, for example, a horror movie before falling asleep, it is very likely that there will be an unpleasant night. So at least our bio teacher. Look at pictures or something. So I have no personal experience because my dreamless nights are better yet.

More precisely your subconscious mind. This is the part of your personality, so to speak, working "in secret" without even realizing you're aware of that (hence the name). Surely you've seen it before, that you've thought about something and suddenly you had an idea, an "incident". Here before you is an unconscious thought suddenly become aware. And that proves that your subconscious mind is always active. Of course you can not remember his dreams of many things from his own past. But what was never recorded with his senses, is also a non-accessible. Of course you can read books or watch movies about the past and dream of then. But "look" is "right" in the past can not. You can not do when you're awake. And even then, not when you sleep. Primitive thought believes that the future is something like a "reverse" the past. As you may remember the (no longer) existing past, one would somehow also in the (still) can not see existent future. In fact, there is a great difference between the past and the future: The past is something that has really given. Future, however, is something that does not exist yet. And what is not there, then you can not see, no matter what you try. Can you force yourself to dream of something? In the dream so often you deal with the problems of the previous day - especially if they have a not "let go". At the same time in the sleep waking consciousness so reduced or not even there. But there are many different kinds of intense sleep. And since then it is actually possible with some training to control his dreams, to some extent. This will only work if your subconscious does not currently holds other things more important. Often it can be, therefore, that you think of something specific to sleep and begin to dream about it - but then suddenly takes an unexpected turn and dream of running off by themselves. That is just exactly as if you're awake and think about something: one thinks in one direction and suddenly nothing will fall as it were something else and you change the subject. You're probably not crazy at all. On the contrary, it is quite normal that you look at these questions represents.
