Is it normal that i dream about my favourite band all the time?

Basically, I dream about my favourite band almost nightly. At first I thought it was a phase but I'm even weirding myself out now...
The dreams aren't particularly strange - I just dream that I'm meeting them or they're performing somewhere near me (most of them take place where they come to my school), and I had one last night where I had a long conversation with one of them, although I can't remember any details of what I said or what she said.
I don't go crazy over them in real life, so why is my subconscious being so obsessive??!!
