Well. Dream vision is incredibly vivid. More pixels than real life.
Dream vision features :1) Multi Focus : where you can see both far and close in detail at the same time. This doesn’t happen in real life, you can either see far or close in detail.
2) High resolution : more than real life
3) Extremely High Contrast Ratio : The difference between white and black. Unexplainable
4) Tunnel Vision : Yup dreams have this. The only other way to get tunnel visit is if you have a massive adrenaline rush. Like when someone points a gun at you. Its hard to get at first but you can master it. (tunnel vision is when you kind of only see what you want to see, the rest are just black. It kind of gives you a zoom like effect)
Hearing : More or less the same, but you can hear stuff far away. Not really that cool.
Taste : Feels just like real life. Except in dreams, everyone is a great cook.
Touch : Hyper sensitivity : feel stuff with way more sensitivity than real life
However it mostly depends on the dream, you will be able to get more of these features as you master LDs
Think about what avalinah said : if reals weren’t real why do we get fooled by them every night. I once dreamt like i was married and i actually went along with it. The logic part of your brain will be sleep so whats in the dream is as real as things can get.
