The meaning of dream about walking is a fairly simple one to grasp, because it is a symbol for progress. A step in any direction in real life is making progress as long as it isn't in the opposite direction, so a steady walk forward means steady progress. Walking is a dream symbol for levels of progress. The slower you walk in a dream, the slower your progress is, but as long as you are setting your own pace, the dream dictionary determines that you are still progressing nicely. On the other hand, the dream meaning of walking against resistance, such as huge gusts of wind, or walking in sand signifies that something is impeding your progress. Even though you are putting your best foot forward, your progress is being slowed down by something that is no fault of your own.
Another dream interpretation of walking is that you are reaching a goal. Progress is not progress unless you have a goal to reach, so if you have been making great strides towards finishing an important project or undertaking in the waking world, you might find yourself walking in your sleep.
Some sources say that there are different dream meanings for walking against resistance. While most agree that this does indicate a failure to reach your goals, some dream interpretations state that impeded motion is the fault of the dreamer. For example, if you have been putting up roadblocks yourself that are keeping you from progressing in a project, then you might find yourself walking through sand, or walking with much resistance. It can also symbolize a kind of mental reluctance. Perhaps you are unaware of something in you that secretly wants you not to finish your project. You are subconsciously preventing yourself from doing the best that you could be doing.
Finally, if you see someone else walking ahead of you, while you are doing your best to catch up to them, it could relate to feelings of inadequacy. Essentially, anything that prevents walking in dreams is a bad sign, whiles any progress forward that is being made, even if it is slow, is a good sign. If you are dreaming that you are walking and then come to a crossroads, this could be a sign that you expect a very important decision will need to be made by you on some matter coming soon.
Walking has a lot of significance in the dreaming world as far as dream definitions are concerned, though few people realize it because walking is such a normal activity. Walking is just as important as the fish or the dinosaur that some people dream about though, and should be considered as such, even if it is not as immediately exciting.
