Your dream is full of anxiety, busyness, tension, repeated discovery of loss, search, and finally fear, concealment and worry, which clearly shows that your dream is full of negative experiences.
So judging from this dream, you have been under a lot of pressure recently, full of anxiety, uneasy about something and worried about negative results. Of course, it may be true or it may be caused by anxiety.
In the dream, the reason why "mobile phone battery" appears frequently in the second half is because this "battery" represents a "knot" in your heart. You are also afraid that it will be exposed, that it will be known, and that it will become a reality you don't want to see. However, the specific meaning of this "knot" has to be solved by yourself. After all, I don't know your life background or what happened to you.
Suggestion: In any case, you should learn to adjust your emotions and calm yourself down. Things may not be calm, but your mood can be adjusted, and you can better face and deal with it after adjustment. For your real heart, find it and try to untie it. Don't immerse yourself in the mistakes you may have made. This has become history. The most important thing is to learn from it and not make the same mistake again.
Wish you all the best!
