All humans have a bit of primal nature in them and feel a little connected to the parts of them that are more animalistic and less human. We tend to think that our being human exonerates us from ever having to feel in touch with nature, or we think it gives us some sense of entitlement to feel more important or dignified than the animals that we share this earth with. The truth is though, as intelligent and dignified as humans are, we are all still animals on the inside and in our most basic elements. If you have a dream where you are eating beef then what this means is that you are trying to re-commune with those parts of yourself that make you a little bit more animalistic.
This is actually a good thing. As important as it is to remain composed when you are around others, sometimes it is a good idea to let your inner animal out when you are alone. You need to in order to be a more balanced individual. The way that you are eating the beef is also important because it decides to what level you want to take your animalistic urges. Are you cutting it precisely with a knife and then chewing it slowly? Is it a well prepared steak? Perhaps you are taking the rarest side of beef imaginable and ripping into it with your teeth, chewing vigorously and hardly pausing except to swallow. Each of these scenarios indicates a different level of that animal desire. Which one are you?
If you dream that you are eating beef, another interpretation of this would be related to the other definition of the word beef. Because we have no way of conceiving the other definition of the word “beef” than the physical meat, this is the only way that we can perceive it in our dreams. However if you are in a fight or argument with someone else then you might dream of beef, because you have a “beef” with someone else. Are you mad at someone or are they mad at you? This is one reason why you might be dreaming of beef.
If the beef in your dream has gone rancid, this implies that you are losing touch with your inner self. When we go outside we put so many layers of protection around us to keep other people from being able to see our true selves. We try to keep our true desires a secret so that we cannot be embarrassed by them. We want to be able to hold ourselves to a higher standard. However, when we are alone we need to let those desires out and become all that we truly are. To suppress yourself even when you are alone would mean losing an important part of yourself, and you do not want to do that. If you see rotting beef then try to do what you want to do more often than not to make up for all of the past suppression of desire. Hopefully it will work for you.
