ELI5:Why do we so easily dismiss reality whilst dreaming?

Dreams are often filled with situations and scenarios well outside of the realm of plausibility, so why do we accept these as being nothing out of the ordinary whilst in the dream-state?

There's a part of your brain, lets call him bob. Bob is a very particular fellow, in fact so particular that when he see something he doesn't like he lets EVERYBODY know. Bob only likes things that fit within his view of reality. So if you're playing a game and a graphics glitch occurs, he lets you know, a robot that almost looks like a person but doesn't quite, he lets you know. But when you are asleep, Bob sleeps with you whereas the rest of the brain doesn't.
