Possibly, but more likely yes. Dreams can and are usually signs of what will happen in the future. What was your dream about, if you would like to describe it? People, objects and colors are some ways to try and interpret your dreams.
certain dreams, yes, a theory about dreams is they're your mind working out a problem, or trying to warn you of an event because subconsciously you picked up on things you wouldn't normally, and your dreams is warning/telling you, but through symbols. i can predict the future through my dreams, never good things though. try and write down as much as you remember of your dream and interpret it, since your dreams are telling you things. i hope it was something good, i normally predict death, divorces, and a few near drownings on my part. one time though i foresaw a new candy show opening up and it happened ^_^ [looked identical in my dream so i had to run outside to get my wits back]
Dreams can be about the future, but the future is not yet set in stone, it will always change, depending on the path you take and what you choose to do in life.
But having dreams of the future can show you what it is to come in certain events that are currentely happening your life. Seeing dreams of future is what is known as prophetic dreams. Prophetic dreams show us what is going to happen in the near future. But like i said no future is set in stone, dreams tend to tell us what is going on with our lives currently. And try to help us sort them out. Even if in a bad situation. Its always a good idea to watch out for signs that your dreams are trying to tell you. Even if you don't understand them you can always get some some help from someone who knows how to intrepret dreams.
If your having trouble remembering your dreams, the best thing i can suggest is a dream recall. Dream recalls can be done while medtiating. But also dream recording is the best solution. Always try to write or draw down what you saw in your dreams. EVen if they get scary. Remember dreams can not hurt you. But they can help us.
