Like everyone else has said, dream symbols are very much a personal thing, and they can mean different things at different times. It also depends on what type of dream you’re having (and there can be different types).
I agree with the general principle of what @Skadoosh is trying to convey - you need to figure out how much of your time and energy you want to spend trying to figure out why it’s coming up for you. You could ask yourself what subliminals are you running, and can you see any connection between the symbol and some aspect of your goals in running the subs? Or is the symbol perhaps coming from a completely different place and it’s just your mind trying to tell you something it doesn’t have the right images to tell you about directly?
Revelation of Dreams is definitely a handy little tool, but it’s mainly for people who are wanting to explore that aspect of themselves in more depth. And only you will know whether that’s something that interests you.
All I can say for certain is: if you approach the realm of dreams properly, it’s definitely not a waste of time. If you want a bit of inspiration… and there’s not much info on this topic out there easily accessible… look into the Russian dream hackers, a lucid dreaming group from Russia from the 1990s. TIGER123 (a young YouTuber who every now and then puts out a video I find interesting) did a video on them a while ago; I think there’s about one other major YT on them I found at one stage, but the data is really scattered.
Basically the moral of the story is they found that if you start mapping out your dream reality using a dream journal or whatever techniques when you wake up, you’ll start to find certain repeating themes, and the process of mapping out the geographical locations in the dreams ends up giving you more clarity in the dream realm, more lucidity. They also found a bunch of much more interesting consequences which is what made the story such an underground internet rabbit hole for a while. Rather than boring you with the story, if you’re interested to learn more, it seems Third Gate have put the archive back together of some of the old material. It might give you a few hours of amusement.
I’m obviously not sanctioning or recommending anything from the site, only dropping this to point out that there’s a lot more to dreaming than most people are aware of. And the absolute critical key element in your life you want to focus on if you want to start understanding or gaining control over dreaming, or more lucidity, is to learn how to concentrate. The more you can learn to enter flow states where your mind is one pointed (which is something there are programs available to help with on SC), the more likely that you’ll be able to find the reason behind the symbols you encounter in your dream, by entering more consciously into that realm when you sleep. Concentration / meditation to that point of flow state also has a lot of other big benefits that will help you use the subs to the maximum extent to accomplish whatever it is that you are after. Really it is a lack of focus, a scatteredness, that stops ordinary people from becoming legendary. You can start by making it a game to be more fully present in your actions/body and environment whenever you’re just living ordinary life, whether it be making a coffee, chatting to a girl or going to work.
