Weird Experience (Slight Ickiness Warning)

So I was on a train, and I went and got some water to drink. Now most of these Amtrak trains have little cups that can be pulled out from the thing holding them, and there is a little water dispenser, next to the bathrooms. On this train, I didn't see that. However, there were cups inside the bathrooms, so I decided they must expect us to use the little sink inside the bathroom. So I drank some water. Then I stepped out of the bathroom, realized I wanted some more, went into the nest bathroom, and got some more water in the cup.

I noticed it was an odd brown color. I had a thought that water was not supposed to be that color and a thought that it was probably some horrible thing that would make me very sick. 

I drank it.
Have I mentioned that I have this brain/action disconnect where weird things around me do not affect my actions because it takes so long for me to process those things?

So after drinking it, I think "I should not have done that." I spent a few minutes imagining future days sick on a hospital bed. I was kind of worried. I had the thought "Well, maybe it would be safer if I threw up." After deciding no, I won;t do that, and being relieved to avoid the disgustiness of throwing up, even if at the cost of horrible sickness, somehow I ended up deciding to try to do that.
So I went back to the bathroom to make myself throw up. For some reason I thought it would be really liquidy...it had been several years since I'd ever thrown up, so I had this idea that I could jsut stand over the sink instead of the toilet. Not sure why I wanted to do that. After several moments of sticking my fingers up my throat it seemed that it wasn't going to work. I was relieved to be freed of the potential disgustingness. Yet, I persevered. With no nausea, a bunch of stuff came out. Unfortunately, it was not perfectly liquid, and I realized it was going to sit in the sink and gross out some poor innocent passenger. So I tried more over the toilet. It is amazing how one can vomit repeated times, and it is amazing that one's stomach can hold so much, so much more than one would think.
