What does my dream mean?

I was at a bar waiting to order a drink. When the bartender gets to me she was so rude! So I was like, " I got something for this broad!" I tell her what I want and when she brings me my drink I tell her I don't want it. Now she's pissed and I'm telling her about how rude she is when I feel something painful in my back. I get up, rush to the bathroom and run into a stall. Each stall had a mirror in it so I took off my shirt to look at my back. I see the stinger of a scorpion poking out of my back. I'm like WTF, and I pull on it, didn't have to pull hard when a black and red snake comes out my back. The snake was long as f@!k!!!!!!!!! And it just curled up on the floor. Now I'm terrified but I didn't scream or run, I'm looking at it like how in hell did this come out my lower back! I picked it up like I was on animal planet or something, right at the head and I had a serious grip on it to examine this snake with a scorpion stinger. I took a look at the toilet put the snake in there and flushed! I watched as this black and red snake flushed away put my shirt back on like nothing happened and went back to the bar! For some reason this dream is on my mind, what does it mean?
