Firstly, in dreams and visions a CROODILE symbolizes a dangerously sly or shrewd person. These people are evil forces or evil powers and there are a lot of demonic activities at work in their lives. They are really powerful spiritual predators and should be considered dangerous.
I would just like to mention that in dreams and visions direction and movement is very important. Every direction that an object is facing or moving in reveals more to us. Different directions change the meanings of dreams and visions.
This dream speaks of a lot of evil powers and demonic activities which are at work in this pastor and his wife’s lives. People that are attacking their ministry and personal lives. They are trying to destroy them and their ministry completely and cause them to lose hope. These evil powers are very dangerous and are trying their uttermost to stop God’s work. The crocodiles coming closer could suggest that could be so called friends that are sly and actually turning against them. Fortunately, they turned to the right which in dreams and visions indicates that although negative, the experience will have good and positive results in their lives. When a symbol moves to the right in dreams in visions, it speaks of God revealing that victory is on the way and deliverance usually as a result of repentance or prayer or authority taken in faith. They can definitely look forward to victory in this negative situation. They must just continue praying fervently and continue to take authority over the situation in faith. Everything will work out for their good” (Rom. 8:28) God is actually exhorting them in this dream.
