Can anyone help me interpret this dream?

here's what basically happened in my dream, i'll try to keep it short as possible.

I was going to a festival at my church in the wintertime. my brother pointed out that we got free tickets that day so we went to get them. It turns out that Justin Beiber and my grandma were handing them out. My grandma said to me, "This is Justin Beiber." I said, "Hi, Justin Beiber," and he replied, "Why do people always use my last name?" so I said, "Do you want me to just call you Justin?" and he smiled. then, they needed help setting up for the festival so I took charge. My brother's friend asked if he could help, and I said "Sure go to the snowforts." then I went to see how the ice sculpting was. My friend Mike was there and for some reason he asked if his sleeve was rolled down all the way. I said yes, and then the dream changed and I was getting confirmed. Me and a few of my friends sat around a round table. My friend Erik sat across from me but then he got up and sat next to me. Then Jesus appeared and started cracking jokes with Erik. Then, they showed us an episode of the Simpsons where Bart and Lisa caught on fire or something. and thats all I remember.

If anyone has any idea WTF this means, please help !!!!! thank you !!!!
