Who cares if it sounds stupid to your ear or doesn’t make sense. No one has to read it if you don’t want. It doesn’t need to be perfect.
The thing troubling many of us, I believe, is self doubt and fear. It creeps around us morning, noon, and night. The irritation of not writing more in those hours we set aside while bad posture remains to be a source of discomfort for some as the next day approaches.
We realize writing something, no matter how bad, is better than nothing when trying to fall asleep.
We try so hard to make it the best we can while we punch the keyboard, forgetting the expectations we place on our shoulders, and other times not so successful.
So yes, write anything. Don’t sit there. Just write.
