What is the meaning in a dream of Arresting

Arresting

I was at the zoo and saw a stampede of alligators. I went into an alcove where there were other people. The alligators came into the alcove. I fed one tiny crocodile and one person cookies. A chicken walked by and the tiny crocodile ate it. As it was eating it, I ran out of the alcove and saw a huge alligator. It came after me, but then went after someone else. I used that chance to escape and when I escaped the zoo, I got the attention of a police officer who was arresting a gang, to help the people left behind.

I was making tea in the kitchen of my grandparents flat and looked out of the window at our local church. There were police, forensics and a grave was being dug up. I felt extreme panic as I knew I had murdered someone and buried them there on a freshly dug grave and I knew that I wouldnt get away with it. Then suddenly I am at home worrying and there is a loud knock at the door. When I andwer it to a cid policeman ha reads my rights arresting me for the murder of..........?? Always wake up before I know who it is. This has recurred numerously
