The problem is, you might dream the joke is very witty, but when you wake up, you realize it is completely nonsensical.

Your brain didn’t really dream the joke. It dreamt the emotional response to it. The joke itself was just a prop.

Not sure where I’m going with this.

Also happens with drugs, the you understood everything thing, teleportation, repetitions, etc, repetitions, etc.

We get used to our usual normal-functioning consciousness, but there’s a whole universe of its potential modes and what-causes-what and in which order. For example, dream scenarios may easily happen in reverse, from a random emotion to drawing the scene around that, to the sense of reality, when you just remember a concept of it. Everything can be backwards, orthogonal, not in order. All “it” has to do is to make it feel normal. All these “backwards”, “normal”, “time”, “because” are not something just granted, you have to actively experience these all the time.

In that case, it wouldn't still be funny and unexpected when I woke up.
