Contrary to common beliefs, only you or a person who knows a great deal about you can interpret your dreams. The symbols you see in a dream don't have universal meaning and you are the only person who can understand what these symbols.
Do you fear cats? Then certainly seeing a cat in a dream would have a totally different meaning than if a friend of yours who loves cats had the same dream. Begin by writing down all the symbols in your dream then try to understand what each one means to you.
Seeing a cat means bla bla while seeing a dog means bla bla. These lists aren't designed to explain your unique personal relationships with these symbols; never depend on them.
What are the most important events that you have been through lately? Did you quit your job? Did you get in a fight with your best friend? Did you break up? Write down a list of all of the serious things that have happened to you lately.
So you lost your money in the stock market and you then dreamt about your teeth falling out. Couldn't this dream be pointing out the fact that you lost some of your power? If you believe money is power, certainly this is the meaning of that dream (see why we dream in symbols).
Even the people you see in dreams can be symbols. Your mind might be referring to someone else when it shows you a certain person in a dream. Don't assume that all the people you see in dreams are the ones your mind is really referring to (see Why we dream about people).
Sometimes you might wake up in the middle of the night remembering your dream then when you wake up later in the morning you remember nothing. The best way to prevent this from happening is to write down the elements of important dreams if you happen to wake up in the middle of the night.
Your mind could be reminding you of an existing problem so that you could work on solving it. It could be motivating you to take action or it could just be sorting new events that happened so that you can accept them (See Why we get recurring dreams).
Let's suppose you saw 5 symbols in a dream. In order to make sure you got the dream right, all 5 symbols must perfectly match a certain event in reality. In other words, don't guess the meaning of 1 or 2 symbols only then assume you got it right.
Most dreams are mere reflections of things that had already happened. Don't mistakenly think that most dreams refer to the future. While visions are not uncommon, still the majority of dreams point to the past and not the future.
If you see yourself falling or flying then it might be tempting to assume that this dream has universal meaning, but unless the dream can be connected to your own unique life, the universal meaning should be discarded.
Your mind might be trying to send you an important message. So pay attention to the personal meanings of your dreams in order to understand what your subconscious mind is trying to tell you.
