According to common sense, releasing a hydrogen balloon will only go up, and even if something blocks it, it will not rebound so much.
Hydrogen balloons are my favorite things. According to common sense, people mostly tie it with ropes to prevent it from flying away.
So for your dream, I think balloons represent things or people you like.
For some reason, you have to make a decision to give up
The people next door are playing it,
Explain that you think there are people in society who have the same experience as you.
After flying, it was blocked by something and bounced back. This is your inner worry. You choose between giving up and coming back. Finally, you caught it, indicating that you are still unwilling to give up this favorite thing or person.
Show it to your friends. Your friends represent the people around you. They refer to your parents, relatives and so on. So make it clear that you still care about other people's feelings.
Finding other people's balloons, I believe, represents the hope that others can set an example for your reference.
As the number 25, I believe it represents age.
The dream is:-Chaos and ambiguity.
Don't take dreams seriously. For reference.
