Being sick means suffering. The stronger the ability to bear pain, the healthier the body, so illness means health.
Dreaming that a classmate is ill means that the classmate is in good health, but recently you may feel unwell because of your negligence in taking care of your family, which is an ominous sign.
Dreaming that a classmate of the same sex is ill means that your recent interpersonal fortune is not good and you may quarrel with him. I suggest you pay more attention to your words and deeds and avoid disputes.
Dreaming that a classmate of the opposite sex is ill shows that his friend has a bad fortune recently, has a dissatisfied attitude towards his friends around him, and feels isolated or lonely inside.
Case study:
There is a young man who has just entered the society and is working hard for the future. One night, he dreamed of collecting money with his classmates, as if on the school playground, and the ground was still wet, so everyone hurried to collect money. In the end, everyone took the money for dinner, and when the money was not enough, they also got together.
Dream analysis: this dream is auspicious. I dream that I can't find money, which means that I may be a little short of money recently, and I hope I can get something to supplement myself. However, the money in the dream sometimes symbolizes other things and other gains. Money is found in the school playground, which refers to the gains within the scope of knowledge, such as the opportunity to get training or the improvement of working ability. The ground is still wet, reflecting a bad mood, which may be an escape from the real pressure. Everyone eats with money, expressing their hope to have a more harmonious relationship with people around them and share all the gains.
