gun dream

I dreamt that I was in a bed, me, my youngest daughter, some other children that I could not see, and I think my husband was there. The alligator would come to the head of the bed and trying to crawl up and attack the children, when my husband and I scared it away, it would try the foot of the bed and we scared it away. This alligator tried this several times until I got tired and angry and decided that I would get a gun (gun looked like a small shot gun) and I grabbed the gun and said the next time it comes I will kill it, but the alligator never came back.
