With understanding of the basic urges and the way to manage them we can create a firm foundation. From there we can progress spiritually. When there is a need to understand why we do things, we first need to control our basic drives. Many reptilian dreams are about control or management. Control of a crocodile would suggest some fear of an aggressive nature. Feeding a lizard or stroking a snake symbolizes taking care of our natural basic urges. Reptiles in dreams link with our basic and instinctive reactions and responses. When there is a basic urge such as a need for food, sex, etc. we sometimes cannot face it full on, but will symbolize it as a reptile. You might find it helpful to consult the information for Reptiles in the Animals entry as well as the entry for Crocodile.
