I think this song is more about general situations in which you can't trust yourself, especially when your subconsciousness starts to do things beyond your control.
For example if you fall in love with a person, everybody tells you to stay away from her/him, but of course you know it better than everyone else. When "emotion takes over the rational" you are not able to focus on clear thoughts. You're wondering, if it's really like you see it, or just because love is blind. You just can't be sure anymore if what your mind tells you is actually true or not.
Your "mind goes into overdrive, to process and deceive" you and you start to lose faith in yourself. To get all over this, you have to "halt the fictional mind", "block out all that makes it painful" and finally "set the pieces back in place".
Of course this also fits to depression or other states of mind out your control.
