How should I interpret this dream I had last night?

I would agree with your interpretation but I may add that based on the way you ran over the alligators you will be able to avoid being affected by these friends that may betray you. Instead you will overcome these situations by believing in yourself. Perhaps in the end the road will lead to someone you are in love with facing a seemingly serious situation which will turn into something that is easily solved. For instance, when alligators open their mouthes they shut their eyes, so in your dream you may have been able to overcome this intimidating obstacle.
