brainparked
An extended period of time when the mind feels blank. No thoughts are going through the mind, but the mind doesn't feel empty either. The term is typically used in past-tense, as an individual can only retrospectively realize that they were brainparked. If an individual realizes that they are in "brainparking" mode, then at that moment they have already left the state of being brainparked.
Sorry, I didn't hear you. I was brainparked for a while.
brainpark
A conceptual compartment in the mind where an individual can be completely devoid of any thoughts. When a mind is in the brainpark, the individual does not experience any thoughts. The feeling is not of mindlessness or emptiness either, but a feeling of restive stasis.
Sorry, I didn't hear what you said. I was in my brainpark for a while.
Please pay attention. I think you were in your brainpark for a while.
