somebody good with dreams?

So I had a really bad dream last night and I have NO idea what it means. I was hoping somebody would help me understand it a little bit. Okay so my boyfriend and I have been together for 4-5 months and I am completely in love w him. I'm 16 years old and this is my first serious boyfriend. He's not that normal 16 year old where he fucks around. He is a man of character and is very sweet and respectful. Last night, I had a dream like I checked his instagram and I had been taken out of his bio and he deleted all of our pictures. So, I FaceTimed him to ask what was up. There was another girl there with him and I don't even know who she was. But as I was asking him, he acted like he didn't care at all... which is the complete opposite of how he really is. I started crying and screaming as I would do if it was real life. But he said he didn't want me anymore and that I was a terrible girlfriend. Our relationship is built on trust and a good understanding of each other. We give each other equal respect so I don't know where this came from. Help?
