There is no one better able to interpret your dreams than you are.
Self-interpretation offers records of how you interpreted your dreams and how subsequent events matched those interpretations.
From this contrast, a pattern will emerge that is unique to you and your dreams, and how you tend to interpret them. When you find mismatches, you have found a learning opportunity.
Detect Precognitive Dreams
There are many unverifiable accounts of precognitive dreams, but you have a chance and the tools needed to prove your precognitive dreams. Precognition in dreams is more common that we understand.
For example, after the 2001 terror attacks in the United States, people reported having dreams of airplanes hitting buildings, or buildings on fire before the attacks.
By journaling and interpreting your dreams, you are creating verifiable records of such dreams, should one of them happen.
Save your precognitive dreams.
