I had a dream that my best guy friend hugged me?

I already have a crush in real life.. But, instead of my Crush hugging me in the dream; it was one of my best friends.. In the dream we met in the hallway at or high-school like usual and we have a short conversation that seemed normal at the time. But then, he takes a step forward and hugs me, which I take a moment to process, but gladly accept and slowly hug back. I could literally feel myself blushing in the dream so out of embarrassment I clutched onto his jacket sleeve that he was wearing and looked up at him. He only smiled and looked down at me.. Then the rest of the dream was kinda fuzzy now until the end, which ended with me hugging him this time, but he accepted and hugged back. So, does this mean anything? Is this the way I want him to act? or.. am I just developing feelings for him without even noticing it?
