What does my dream mean?

I was laying with but kind of on my best friend's brother (who is also kind of my friend) on his bed, and he was in his boxers and he was wet and I said to him "why are you wet are you sweating?" and he said "no I just got out of the shower" and I said "oh okay" and he said "okay goodnight" and then i closed my eyes to sleep, but all of the sudden I felt really anxious, so I got up and left.

Please help! thanks
