Here is an Eitza I saw in the sefer Taharas Hakodesh. This is for the times when y.h. is running freely in our minds, filling us with all kinds of 3D thoughts, pictures etc.
We see in the kapitul:
לדוד בשנותו את טעמו לפני אבימלך ויגרשהו.
Avimelech captured Dovid hamelech. Dovid Hamelech saved himself by acting liking a meshugah. If it was known that it was in fact Dovid that he captured, he would have killed him immediately. When Dovid Hamelech acted like a mental case. Avimelech came to the decision, this cannot possibly be Dovid Hamelech. And, this is what saved his life.]
He explains that:
Avimelech is the klipah, the tumah, i.e. the y.h. He says that even though the y.h. is a דבר רוחני
nonetheless, it still needs chomer (i.e. the brain) in order to dwell with is. Without the brain, without having the Kli, the y.h. this klipah, cannot attach itself to us. So, when we do what Dovid Hamelech did, i.e. be mevatel our brain, and act like a complete meshugah, this klipah, cannot stick to us.
So, when the y.h. begins to take over our minds, attaching himself to our brains, we are to do what Dovid Hamelech did. Go to a private room, stand opposite a mirror, and do your best job of acting and turning yourself into a complete mental case. THis means to do what Dovid Hamelech did. Start to moan, groan, and make all types of strange sounds. Distortate your face as much as possible, and stick out your tongue, spit, and salivate etc.
When we have temporarily removed the capacity of our minds, the y.h. has no place to cling and attach itself. This is what saved Dovid Hamelech. As it says: ויגרשהו וילך
