To dream of a meteor represents a potential problem with the ability to devastate goals, plans, relationships, or your sense of stability. Unexpected problems with the potential to be serious. Feelings about radical change, potential catastrophes, or enormous unwanted impacts on your life. A major event. Significant unexpected disappointments.
Alternatively, a meteor may reflect feelings about large unexpected changes that don’t really effect you personally. Witnessing something big changing for someone else. Hearing about big change on the news about a foreign country.
Example: A man dreamed of seeing a meteor hit the moon. In waking life he had experienced the September 11th attacks on the World Trade Centre on the news.
Example 2: A young woman dreamed of seeing a meteor hit the ground. In waking life she had discovered that her boyfriend had found out about her cheating on him earlier in the relationship.
