Could this be proof that dreams could sometimes tell the future?

I believe in dreams... I once dreamt that my boyfriend, his ex, his best friend and best friends ex, were all at the hotel. I woke up at almost 4am noticing he was gone. (it was normal for him to go out drinking at nights), but at this time of night bars in our area had long been closed. I called the girlfriend of his best friend and she didn't know where her boyfriend was either. Around 5am my boyfriend got home. I asked where he was... I forgot his excuse, but it wasn't the truth. The next day, I checked his online bank account where I saw a $150 transaction to the Marriot. where he had been "chatting" over popcorn with his ex, his best friend and his best friends ex... I have believed there is definitely some truth to every dream.
