I Had A Crazy Dream Last Night

Last night I had a dream that my best friend was having a party. When I got there, I noticed my ex boyfriend was there with his brother. I didn't say anything and just went and sat down. So, when my friend came down and joined the party my ex had the nerve to say hi to her, and pretended as if I was invisible. I told him he was rude and he started to tell the whole room I cheated on him (which is hilarious because he was the one cheating on me the whole time I was with him), and that was infuriating me to no end. All of a sudden everyone, and I mean EVERYONE was out of the room. It was just him and I. I pushed him out of the stool he was in, raced over to the kitchen sink and filled up a pitcher of water and threw it on him while screaming. Ah. Anybody know what this dream means, like the significance of the water?
