This sometimes happens to me when I get a migraine.

A sentence can be coherent in the formulaic sense, but complete nonsense as far as words. I immediately notice that it's incorrect, but I don't have the ability to fix it at that moment.

Yes! I immediately noticed that what I said was wrong (even though the word I said still felt somehow connected to the thought I was trying to communicate). I was really worried at first when it happened because at the first time I had no idea sleep deprivation would cause this, or that I would experience it.

I had no idea migraine causes this as well, interesting.
