dream really came true???

Date: 3/24/2017

so I had a dream about a week ago that my boyfriend was cheating on my with a girl from my work. I was kinda mad at first but I told myself it's just a dream. the only reason I remember is because I wrote it on my dream walk. so today he tells me he has been cheating on me for a few weeks but wouldn't tell me with who. I said " I know it was with someone from your work" i just knew. He kept denying it but he finally told me I was right. Then i was thinking like how did I know that &I remembered my dream. crazy.
