Is it normal i had a dream where i was black?

Normal. I've had different dreams where I was Irish, Black, Jewish, Buddhist, tall, short, male, a child, a chicken, an anime character, and even a goddamn shoe. Dreams are so weird sometimes. XD

I had a dream similar where I woke up looked at my face in the mirror and I looked Chinese for some weird ass reason and started to randomly speak Chinese for some odd reason in that dream.

Strangely enough, I too had a weird dream related to blacks recently. It's really strange since there are no black africans in my country (or at least my city). There may be just a handful in the capital.
I saw myself from the back, being around 5'10-11 and heavily built though unathletic white rapper. Alt-right style, untrimmed goatee beard and dark greenish cargo pants. I opened the door of a black luxury car where a large bald black man in his 50s was sitting, wearing a black suit. Exchanged twice, not recalling what exactly but obviously heated and with prehistory. He proceeded to try to exit and push me out of the door frame and I produced a dagger and stabbed him in the skull, on the top of the head, blade going at least 3-inch deep. To which drums sounded in the background like in some Jackass show or Idk what.
Consciously, I don't condone such attitude though.

omg i hope you're ok!! i get nightmares too :(

I once dreamed I was a witch, but didn't need a broom to fly.

Heck yeah, it's normal. I've had dreams that I was Michael Jackson, that I was a literal anime character, and dreams where I looked Asian even though I'm white

Hell I cant even remember what I looked like in a dream. I'm practically like a first person charicter in a videogame. At best just a pair of floating arms with a body shaped shadow.

im sure this is somehow horribly racist
