I think you are right. The totem pole represents the history and customs and practices and influences of Hollywood. All these things became an obstacle to you. This also implies that it did not become a stumbling block but rather an obstacle. It could not hurt you spiritually but it did hold you back a bit. That is what obstacles do. It makes things hard for you and it slows you down. The fact that you slipped is an indication that you almost damaged your spiritual life but you did not. You hanged on. Spiritual deterioration almost became a reality but it was prevented.
Whatever the challenges were, you did beat the challenges and the onslaughts on your spiritual life. The hang on, the reaching the top (victory) and the stood up indicated that you were successful in protecting your heart and your Christian values.
A crocodile symbolizes a dangerously sly or divisive 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 assume an alligator represents the same thing, just not as strong as a crocodile.
So, it may have been an evil spirit but it could also have been a bad person, whom the devil is using, within the movie industry.
It was either your heavenly husband, Jesus Christ or your earthly husband who came to your rescue when this person or evil person attempted to hurt you spiritually.
You were able to reach your destiny, which was to successfully fend off this attack on your life. The enemy attempted to use Hollywood and its people to hurt you spiritually but he could not succeed.
Now the question is, did this happen already, or is this going to happen? If it did not happen yet, or if you are in the midst of the battle, God says that you must persevere. You will make it and He will be with you.
