I find the theme of your naturally independent personality coming out yet again in your dreams. Having an independent streak tends to make us a little more selfish but not in the conventional mean or malicious sense. More like hugging up things more than the norm especially as they relate to your emotions. You are used to solving your problems on your own, figuring out things for yourself, and just generally internalizing a lot. This can serve as a great strength to have but occasionally it can be a weakness too, because it can sabotage you. The dream is suggesting you need to be more of a "sport" and a team player. Share more of yourself and depend on others sometimes. It can be hard, but sometimes you are amaazed by the number of perspectives that open up and expand your knowledge base or better the solution to your given situation when you do at times. The dream can be pointing to emotional issues and also literal issues. I think you have the answer.
I think it may have a spiritual outlook too, it may be your spirit guides trying to reach out to you, they are telling you you need to open up more to them, and trust and rely in their own techniques and advice to help you with your growth. Their ways might be unconventional or unusual to you, but if you open your mind to it, it will be worth it in the end. This is just my take though.
I should also note that the training and team coming up in your dream may also refer to some matter in your life that is causing issues, anxieties and a lack of self confidence. Again the lesson is probably to share more on your problems and concerns and to trust in your spirit guides to overcome such matter(s).
