My dreams vary a lot. Sometimes they're real, sometimes cartoons. Sometimes color, others greyscale. Sometimes I'm myself, other times I'm someone else (like playing a character in a video game), and yet other times I'm simply an uninvolved observer (like watching a movie). It's kind of a grab-bag.
As for gender in dreams, I rarely notice gender in dreams unless the dream is specifically gender-themed. It's not so much that I don't have a gender, just that it doesn't matter enough for the dream to take it into account. I mean, if I take on the identity of a character or something in a dream, my brain sometimes takes into account the gender of the character I am in the dream... but I'm fairly certain me being male in a dream doesn't say much if I'm also an 8-year-old anthropomorphic cartoon MOLE. XD (Actually, though, in character type dreams, I usually take the form of a male animal character. But that's just as a general rule of thumb.)
When I'm
myself in dream, I really never notice my gender unless it's a major part of the plot. For example, here's a rather entertaining dream I had recently (copy-pasted from a different site, because it seems silly to retype the whole description):
QuoteSo, for some inconceivable reason, I was placed in an elementary school to go to their class for transgender kids. I was still this age, mind you, but the elementary school was the only school around with a class for transgender kids, so that's where I went. Said class was taught by my favorite teacher... from high school?! And it was kind of like a special ed class, where there are students of all ages, so it was like... kindergarten through 5th grade, and me. So we had activity time, and I kept trying (to no avail) to find an activity that wasn't about 12 years below my skill level, and was getting fed up when the teacher announced that it was bathroom and lunch time. She then reminded a couple of little girls (who were MtF, of course) that they should be in the girls bathroom, not the boy's bathroom, and I asked which bathroom I should be in. Apparently there... wasn't a bathroom forme, so I just held it.
So then we went to lunch, and apparently all the transgender kids sit at one table (recipie for bullying, anyone?). So I sat down at the table, and lo and behold, I spot a little boy (about second grade) who I recognize from a previous dream-- about teaching! And yes, dream-me remembers him quite clearly from my teaching field experience, because apparently my dream-memories overlap. Aaaawwkwwwaaaard-- my student has become my classmate. I'm very excited to see him, so for some reason I pick him up to say hi, and for some reason the whole lunch room starts picking on him because they think he's a raccoon. WHY? I don't know. He wasn't a raccoon in the previous dream, nor was he (or did he resemble) a raccoon when I spotted him in this dream, but when I picked him up, lo and behold, there was an anthro raccoon in my arms. But I knew the kid, so I kept denying he was a raccoon.
Needless to say, THAT dream I kind of had to have a gender for or the dream wouldn't have made sense. XD
There's only one other dream/nightmare I can specifically recall being
myself (not a character) in and having a gender (or at least... a physical sex) for, and my body was female in that. *shrugs*
