Dream about best friend?

I had a dream last night where my best friend and I had . We are both girls. I am not a , nor am I ually attracted to her in any way. I have a boyfriend that I love very much. My best friend and I are very close and we often play around, like wrestling and stuff and when she spends the night she usually snuggles up next to me. We are both straight though. Is this normal? I feel weird and ashamed about this and I don't know what to think.
