So,i was watching family guy, and I got this idea… Has anyone had a dream in 2 dimensions like a cartoon? If so, what was it like? I’ve been thinking about it, but I don’t know how I would make something like this happen…
Several, in fact. There’s even people who occasionally dream in retro 
Of course, behavior of dreams is influenced by our daily life, so most of the time, it would be like watching a cartoon, or playing a 2D game. There’s been people who have willingly restricted themselves to 2 dimensions in a LD, like Wyvern. You can check out his DJ to read it 
I think it’s hard to talk about dimensions within dreams. Most dreams feel 3D because that’s what we are used to but the dreams might as well be 4 dimensions.
It’s not really necessary to go all metaphysical in this topic, you know 
the question was just if we had some dreams that resembled a cartoon, or a 2D game.
In fact, from my experience, it’s just like watching one, to the point I would occasionally “zoom out” and comment on what I was watching to the others present.
I have dreams like this almost all the time. 
they usually feel like I’m watching cut scenes from a 16-bit style video game (whether it exists IRL or not) unfold. Come to think of I’ve never become lucid during these kinds of dreams but when i can, I’d imagine it’d be cool watching things unfold (or to even manipulating events to achieve a desired outcome)
I have vague memories that Ive had cartoon dreams and perhaps one or another 2d-dream they are rare though 
I’ve never done it before, but I can’t imagine that its impossible.
I had one, really good one, kind of in the world of the anime Bleach. 'Course, I wasn’t really physically participating in it. More like I was controlling my body and speech, but detached, video-gamey.
well it better be easy for me because 99.99% of my wanted dreams are in cartoon form. 
believe me…when i hit lucidity im gonna automaticlly turn myself into some sort of cartoon charecter i’ll try to upload a drawing of my wanted cartoon form soon 
Don’t think I’ve ever had a 2-d dream where I was an actual 2-d character in a 2-d world…but I’ve dreamt that I was playing 2-d video games.
I think it is because my mind has no clue what it would feel like or look like to be a 2-d character. I’m just a 3-d being. : p
How does it feel to be 2D like? 
Body feelings, perception, etc. Tell 
After playing lots of CoD: MW2 for days, I dreamt about it. In middle of the dream, I was wondering why do my weapons change after every death… when I realised that I was dreaming, the whole dream (or the game) messed up and I was like “What_the_f…”
Then I woke up… did not realise to take the control of the dream.
