If you have a dream in which you see a donley or worse, see yourself as a donley then this has many negative things to say about you. If you want to know what it means to dream of a donley or donkey though, then this is the meaning.
If you have a dream of a donley then this basically means that you are thinking about how stubborn you can be sometimes. The donkey is a creature that is known for being very stubborn and also very slow. Perhaps you think these things of yourself because of how you responded in a certain situation that you were presented with earlier. If this is the case then it makes sense why you might be dreaming of this. Try to be a bit more open and a bit less likely to snap at people or say mean things. This attitude adjustment should lead these dreams to stop.
A donley is also known for not being extremely sensitive to the feelings of others. The donkey is, as aptly names as it is, an ass. Someone that you might describe as an ass is basically just a jerk and to have a dream in which you are a donkey this means that you need to start concerning yourself with your friend's thoughts and feelings before they stop caring about you and detach themselves from you. You need to have more compassion to act in a truly human way.
