How come when we literally look at an object we're able to see people and worlds clearly, but when we draw everything looks completely wrong?
Because dreaming isn't drawing and drawing isn't dreaming.
And no, you don't 'see' people or worlds at all in your dream. There is no sensory input (besides, occasionally, sense of touch or sound). Neither do dreams accurately depict reality - You just can't distinguish at the time you're dreaming because your rational processing isn't on. After you wake, all you have is your memory, which you rationalize.
Note that you think your memory of a giraffe is great until you try to draw a giraffe. Your brain does not file away a perfect image of a giraffe (unless you've got an exceptional memory), it files away certain cues that are retrieved when you need it, and any beginner artist will quickly realize these cues are frequently incomplete and flawed. Symbol drawing is symptomatic of this - you're drawing what your memory stores, but you're not drawing reality. If you dreamed of a giraffe, you'd know it was a giraffe but that doesn't mean you're seeing an authentic giraffe (it might be nothing like a giraffe - have you seriously never noticed how many things seem completely normal in dreams that are unbelievable in reality?). Even if you were seeing a perfect image of a giraffe, it wouldn't follow that you'd be able to physically manipulate a tool to accurately recreate that image. Drawing is a skill that needs to be practised, whether drawing from a dream, memory, or observation.
I don't know why I even tried to answer this question, though. I don't suppose you're high, OP?
