Found on /r/insanepeoplefacebook, confirmed not a troll:

The problem started about three weeks ago. I had a dream involving Barack, which is not uncommon for me, I was working with him and Michelle on their upcoming Netflix show. We were looking over demographics and how they related to various geographical locations. Without even realising it, I said “Yeah, N***er, we should do pretty well in (area near me)” He just looked at me and stormed out with Michelle behind him. I woke up and went into the bathroom to splash cold water in my face. I dismissed it. I don’t have a racist bone in my body. This was just one of those dreams, right?

A week and a half ago, I had a similar experience. This time I dreamt we were going wine-tasting together. I don’t remember the lead-up but I ended up saying something to the effect of “The sommelier said we should be detecting earthy tones in this wine, but it’s just not registering with me, N***er” This time, instead of storming out he replied, very sternly “Why did you feel that was an appropriate thing to say?” I began to stutter and explain it was an accident but I had once again woken up.

The most recent incident was last night. I dreamt I was at a family barbecue with the Obamas, just his family and mine. He was manning the grill and i was speaking to Michelle while the children played with each other (I know Sasha and Malia are adults now but I still think of them as children) I said to Michelle very politely “excuse me for one moment” and marched right up to Barack and tapped him on the shoulder. He turned around to look and me and I just said the word and nothing else. I can write off this happening once or twice in my dreams but three separate events is too much.

I don’t know what to do. I don’t want to do this. Every time it happens my work suffers the next day. I’ve started lying to my wife saying I’ve been having nightmares but I’m not sure she fully believes it. Lately, I’ve been worrying I might start saying it in my sleep and she could hear. I’m at my wits end and I want it to stop.
