Confused About Jail

This dream was about

I had to go to jail but I wasn’t sure why or what I did. When I got there I was being admitted but not really told what was going on. It was strange because I still had my clothes and my cell phone. I was wondering around trying to figure it out. I knew I was in jail but it was strange because I had my phone still and there were tons of activities to do. There was a huge water slide probably 5-6 slides wide with plants around it. The slide went around the corner and landed into a pool. There were classes to take and things to do but I still didn’t want to be there. I was able to get to my track and I drive straight to my grandparents house. I knew I was at their house but it wasn’t their house in real life. I explained to them that I had went to jail and I needed them to give me bail money. I was frantic and told them I had no idea what it would cost but I needed out. I left abruptly because I had to get back to jail. When I got back I was still confused why I was there and what I did. I’m not sure if I got the bail money or not.
