Dreams can be the key to the past, present and future. They sometimes hide secret experiences, feelings that people themselves hide from themselves. You should not interpret dreams according to dream books - the results will be contradictory, especially if you take several books, and also, possibly, far from the truth.
Do not take everything that happens in a dream literally. For example, if you kill someone or seduce one of your friends, this does not mean that you secretly dream of doing it. Such dreams are more likely to indicate that you think or worry about this person, that you have some unfinished business with him. If the same relative, colleague, or friend appears regularly in your dreams, think about what this may be connected with.
Trying to solve the mystery of sleep, rely on your emotions. When you wake up, do not immediately try to get out of bed and do business, but lie down a bit with your eyes closed, trying to plunge into the dream you just saw and understand what emotions it causes you. It is your attitude to what you see that will become the key to both the problem and its solution. Suppose if you dream of a building that causes you fear, disgust, and when you leave it, you feel relief, joy, then you should think about moving, changing jobs, etc. depending on what bothers you more.
Pay special attention to the analysis of your behavior and perception of yourself in a dream, since it can also have a special meaning. It may seem to you that the personality itself has changed: in a dream a person can see himself more cowardly or brave, stronger or weaker than in life. Hidden fears, forgotten worries and anxieties may break free, or the other side of the personality may appear, an image may appear that you might like to be like.
Finally, one of the most difficult, but effective ways to solve the mysteries of sleep may be an attempt to talk with his characters. Going to bed, make sure that no one can interfere with you and try to return to the place you saw in a dream. Go there, explore, look for people from your sleep, talk to them. If the same dream is repeated, mentally return to it and change events. Is someone chasing you? Stop and look around, face your fear, understand what worries you so much. Such an experiment may help you understand yourself and fix what bothers you.
