The mule represents the body as a living support for human activities. Therefore, if the animal appears weak, you have to look after your health. A dead mule can express the lack of foundation in your projects and the consequent impossibility of completing them. The oneiric image of the mule indicates evil enemies. If it is burdened, it announces problems; an unburdened mule bodes well for business.

Do animals dream?
Research conducted by various scientists show that animals do experience dream while sleeping. They also experience similar sleep stages like human beings - REM and Non-REM. If you have noticed a dog sleep, it might sometimes wag its tail, this indicates some response to its dream. A study was conducted in a cat by removing a part of the brain stem, which will not prevent it from reacting to the dream during REM. It was noted in some cats they were aggressively chasing mice as in reality.
