This does not necessarily mean that you need to become complacent and accepting of a poor position in your life (if you do consider yourself to be at a poor position in life right now) but it does mean that you need to learn how to take some time out of your schedule and get back to doing things that you love to do instead of slogging through meaningless workday after workday. If you do not enjoy amusement parks at all, that is totally okay, the dream is more of a warning that you need to take time to yourself, not that it needs to be spent specifically at an amusement park. You can still have fun out of that context, you just need to schedule yourself a bit more time to have fun and less for working and doing unpleasant things.
The different rides and attractions and games at the park are usually each representative of certain aspects of your life. Take these into account if you do attend an amusement park in your dreams. Sometimes the games themselves can be pretty surreal too, so playing them while in your dream may give you an interesting perspective on yourself and your inner feelings. Alternatively though this same dream could be to let you know that you have been far too distracted by meaningless pursuits lately. Spend less time at the amusement park and more time trying to figure out your life. You need to buckle down and get to business. The fact that you are dreaming of it shows that your mind is too polluted with thoughts of fun and pleasure for you to concentrate on the things that matter such as your job, your family, and your ability to sustain yourself in life.
If you dream that you are at an empty or abandoned amusement park, what this means is that you need to be more open to new experiences. In this case, the word experiences cannot be interchangeable for ideas or feelings. In this case it really does mean experiences. You need to go out and do new things so that you can have more experiences under your belt. Do not settle into a boring lifestyle. It is this kind of lifestyle, the sameness and lack of change, which leads to depression in so many others. Do not be like the rest. Try to make sure that you are always trying new things and experiencing the best of what life has to offer you. You will know that you are a more whole person once you have done this. If you dream that you cannot ride the attractions at the park because they have broken down, this implies that your life is not going in the direction that you thought that it would. This is even more reason to try new things. Your life is going out of your control, so you might as well live it up while you still can.
