This dream depends on two parts: the first part is "getting married and wearing a wedding dress", which is reasonable and reasonable, indicating that your work and life have been relatively smooth recently, with no accidents. Look at the second half: "crowded bus to get married, ...", which is unreasonable. Do you have some anxious things in your heart, such as losing money or power, or losing the game, failing the exam, etc. "I don't even know who the groom is." It's just that you don't know the result. There are good and bad results.
Generally speaking: you have experienced too little and it has been going smoothly, so you are very entangled in things.
Some things will inevitably happen in life, and not everyone will be unhappy. What's more, the result is uncertain now, but it's not completely certain. There's a good chance. You don't have to worry.
