What is the term for the "knowing what you think but can't explain it" phenomenon? I think we all experience this phenomenon once in a while, and I am experiencing it right now. It's the feeling that whatever word one tries to say it seems to be wrong (for them) or confusing (for the listeners), and would require a period of time to think out the right word that they have already known. If severed, it can lead to frustration, but it's not really about feeling insecurity.

What is the word for that?
Mental block

A mental block is an uncontrollable suppression, or repression of painful or unwanted thoughts/memories. Also can be an inability to continue or complete a train of thought, as in the case of writer's block. In the case of writer's block, many find it helpful to take a break and revisit their topic.
