There are some funny connections that a person can make in their dreams without even realizing it. If you have a dream about a disco or a disco ball then this can mean a few things but the basic premise is that of the opposite of discipline. You need to cut loose and just live life to the fullest. As many sad pitfalls are present in the enjoyment of disco and as many weird nuances and odd customs are there and employed by disco lovers, the thing is still all about having fun, this is why disco exists, it is a way for you to get out of yourself for a little bit and just have some good clean fun. You might have a dream in which you are doing a disco dance or where you see disco balls and all this means is that you need to be more liberal and have more fun. Be more honest with yourself and know that life is all about having fun. As important as it is to buckle down every once in a while you need to also remember that it is just as important to have a good time or else it wouldn't make all the hard work worth doing at all.
One of the central ideas behind disco is the idea of cutting loose, and the idea of cutting loose through disco has never been more prevalent than it is today despite how little disco is actually practiced these days, believe it or not. It is actually because of how little people actually try disco dancing anymore that it makes so much sense as a form of cutting loose. It is something where if a person participates, they begin to feel great shame for having done so. Even in the days when disco was very popular, those that were not in the disco circle seemed to dominate and a great many bullies made fun of the people that did attempt to try to have fun during disco. They would go out and do it anyway despite being goaded and hated by a lot of people but this is where the strength is disco lies.
Dancing is definitely cutting loose in one way, but dancing in one of the most unpopular ways is by far the greater expression of what it really means to cut loose because it involves you getting rid of whatever perceptions someone else might have of you and just living the way you want to and doing what it is you want to do despite how uncool or cheesy it seems. This is the true way to cut loose, and to have a dream in which you are doing disco dancing means that you are too concerned with what the others around you think. You need to break away from the perceptions of others and learn to be able to accept yourself for who you are, let the world accept you for who you are, and move on from there. There is no point in letting yourself suffer over something like this. Simply make the right decision the way it needs to be made and don't let anyone else's perception of you keep you down at all.
