Nothing whatsoever happens if you tell your dream to someone. Persons tell their dreams to counselors, therapists, friends and family members all the time, not to mention to dream interpretors. Talking about a dream has no bearing on whether that dream will "come true" or not.
When you go to sleep and you dream your eyes move in a rapid movement, referred to as REM or Rapid Eye Movement sleep. That is how you tell when someone is dreaming.
it depends on how much you think about it
Nothing "happens" when you dream about crabs. If you mean "crabs" as shellfish, the dream could mean that someone is preparing seafood somewhere nearby while you are sleeping, and the odor is influencing your dream.
It means that it is time to tell them :)
tell them and see what happens
they tell someone.
In some cultures and beliefs, it is considered bad luck to share a good dream with someone else. This is because it is believed that talking about a positive dream may cause it to not come true.
Puck announces everything was just a dream. It is very hard to tell because he is using Shakespeare's confusing language.
This is a wish-fulfillment dream. The mind produces a dream in which the dreamer achieves something deeply desired. It reflects the dreamer's thoughts and desires. It does NOT indicate the "someone's" feelings and it does NOT predict any future events.
It is impossible to provide a reliable interpretation without actual information about the dreams themselves. Very generally, it does not seem that the dream is trying to tell the dreamer anything in particular. The "someone" appearing in the dreams might represent something that is constantly in the dreamer's thoughts. The dream provides no information about that "someone's" feelings, thoughts or condition.
guilt will always get you. if something bad happens tell someone about it.
Of course! You can, by using a dream dictionary, or figuring it out yourself. Write down what happens in your dream or draw a picture of it to help you understand better. A psychic can definitely interpret your dream, not to jump to conclusions or anything lol.
