When I was in school, I always tried to unravel the dream I had. I bought special "Dream Interpretations", looked in them for answers to the question: what does this or that dream mean.
But now I realized - all this is useless.
We just dream of dreams and that's it. If the day was full of emotions, then the dream will be restless, "serial".
I think that dreams are a projection of my daytime impressions.
I am asleep, but the brain continues to work and process the information received during the day, giving me the result of this processing in my dreams.

I periodically have a dream in which a tiger is chasing me. Why a tiger, and not, say, a dog or a bear? Do not know.
But the fact remains: the tiger is dreaming. Big, striped, evil, he in every dream tries to touch me with his clawed paw. He reaches for my shoulder (why shoulder?) And at the last moment I always manage to dodge and remain unharmed. These dreams were hard, sticky, terrible.
I always woke up with horror and then could not fall asleep for a long time. In this case, what did my subconscious want to tell me? Having thought it over, I came to the conclusion that I have these dreams when problems accumulate in my life, that is, the so-called "black streak" is coming.

It would seem that one can put an end to this: everything is clear, everything is explainable. But what if you suddenly realize that something is happening to you that you have already seen once, but ... in a dream? Yes, yes, and I also dream such dreams, though very rarely.
Nevertheless, several times in my life I had “prophetic” dreams.
But then the subconscious has nothing to do with it?

There is another dream that I cannot explain.
For example, I dreamed several times that I was smoking.
I - who have never taken a puff in my life - smoke in my sleep, happily sucking in the smoke, then exhaling it with relish. In a dream, I feel the taste of a cigarette, I smell its aroma, and I like it. I wake up in the morning, remember a dream and ... I don't understand anything. Sleep leaves a pleasant impression, but I smoke there! I can’t figure out in any way - the projection of what events or desires this dream is.
Do you have dreams?
Why do you think we have dreams?
