What does this dream mean?

i am not really a big justin bieber fan but i think some of his songs are OK. i had a dream about him. in the dream we were like really close friends and he was even friends with my mum. i don't remember the dream that well, but it seemed we were just close friends and nothing more. but is weird to me cos i havent even listened to any of his songs lately or even seen him on tv or anywhere else.
