1, it is possible that something you thought during the day led to such a dream.
2. Sometimes I personally think that dreams are sometimes predictive. For example, what happened after I dreamed several times. People's brain ability has not been fully developed. So I believe in some dreams.
3. The advice your dream gives you is to predict what will happen in the future. After 10 months, maybe "10" only represents a certain number or something else. Not necessarily 10 months.
So you just have to relax and move on with your life. Don't make your brain nervous.
