I think that dreams can both foretell your future and some can mean nothing depending on the dream. There has been many cases when for example a dad dreamt that his son would hit a grand slam and 3 days later his son actually hit a grand slam.
Coincidence or not, it’s all up too weather you believe it or not. Another example is the sinking of the titanic, hundreds of people came forward with reposts that they had earlier dreamt about the sinking of a great ship. Does this prove that dreams can foretell the future, maybe, but it also depends on the dream and what extent it goes to. If you dream that for example Einstein will come back to life, your dream might be foretelling the future but you may never know because you will have died before he actually comes back to life. I believe that most dreams foretell the future, maybe like 60% of them.
Dreams, people have dreams all the time, most people over the age of 10 dream at least 4 to 6 times per night. The length of a dream can vary; they may last for a few seconds, or approximately 20–30 minutes. You dream every night but sometimes you just don’t remember it.
In the play Romeo and Juliet, Romeo and Mercutio were talking about dreams. Romeo believes that dreams foretell the future but Mercutio believes thats dreams are just a bunch of lies. I believe that most dreams foretell the future, maybe like 60% of them, I believe that the other 40% are just for your own good. I personally loves dreams because they can be about anything you want, but sometimes you don’t have control of what you are dreaming.
