What is it called when in a two-phrase sentence the second is unrelated to the first? [closed]

When we talk, each sentence that follows is related logically to the previous sentence, for example, we say:

"I get up in the morning (sentence 1) and brush my teeth (sentence 2)"

Sentence 2 makes sense to follow after sentence 1.

What if we say something like this:

"I get up in the morning (sentence 1) and dogs can't fly (sentence 2)"

Here sentence 2 makes no sense and is unrelated to sentence 1. Another example:

"It's cold today but my house is clean".

Is there a name for such phrases?

Solution 1:

The normal description of this is to say that the second clause (not 'phrase') is a Non Sequitur. That's from a Latin sentence that means 'It does not follow', and it can be used to refer to any situation in which something is said that makes no sense in the same context as the previous discourse.

Non Sequitur also refers to any statement in a logical or philosophical argument that's not supported by previous evidence or arguments; that's where the term originated, in philosophy and logic. A non sequitur is the opposite of something that 'follows (from X)'.
